Compiled the kernel from git (for radeon stuff), rebooted. 2. 'ninit' segfaulted, 'ls' from busybox segfaulted. 3. Read your mail about busybox breakage, upgraded busybox with -fno-tree-pta, but... the same segfaults with kernels compiled by gcc-4.5. 4. Played with the kernel config for hours until finding out that CONFIG_CC_OPTIMIZE_FOR_SIZE=y causes the segfaults (and only on x86_64). I wonder whether this is something more specific to my setup, or nobody is compiling kernels with CONFIG_CC_OPTIMIZE_FOR_SIZE=y on x86_64 with gcc-4.5 (building with gcc-4.4 works)... All this is probably unrelated to http://gcc.gnu.org/PR43987, but perhaps it will save some time for someone, as your post about busybox helped me. I'll wait for a new gcc package before reporting a gcc bug. -- -- Rogutės Sparnuotos P.S. The only good thing about the wasted time was that I found out how to use qemu for testing: $ qemu-system-x86_64 -kernel bzImage -initrd initrd.img

[arch-general] Compiz Application Switcher(Ctrl+Tab) crashes X Server

[arch-general] perl 5.12
by Caleb Cushing 05 May '10

05 May '10

Is there a timeline for perl 5.12 entering testing? I realize it's an important not to be jumped into thing... but I don't see any bugs that are obviously holding it up... so I'm just curious why it hasn't entered testing yet. -- Caleb Cushing http://xenoterracide.blogspot.com

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I am new on this list, but not with Arch Linux, I've read in http://www.archlinux.org/news/496/ that you were or are looking for junior dev.

Is there any official announcement about new "dev jr" or something that you will show? any status or something?.

[arch-general] Brasero Wont Copy Disks
by Carlos Mennens 04 May '10

04 May '10

I just installed Brasero to burn / copy disks. I first added my user 'carlos' to the 'optical' group. However when I try and copy a disk on my machine, I get an immediate error that says it fails. Then when I save the log, it's blank. It has no details as to why the copy failed. Anyone know what I can do to resolve this and allow my machine to burn / copy disks? I know my optical drive is running fine because I booted from Ubuntu Live CD and was able to copy a disk fine. Thanks for any help!

[arch-general] What is Arch doing vis-a-vis MySQL v. MariaDB?
by David C. Rankin 04 May '10

04 May '10

Guys, Ran into a shock this morning when on one of my 2 lingering suse boxes updates replaced MySQL with MariaDB. After a brief bit of research, it seems that Monte (one of the MySQL devs) forked mysql into mariadb from the mysql code base in the 12/2009 timeframe when Oracle bought Sun to preserve MySQL and prevent against any funny business by Oracle in the future. According to statements made by Oracle, it is under an obligation to the EU to continue mysql largely in its present form and continue to enhance and make it freel available as part of the purchase. (See Oracle Statement): http://www.oracle.com/us/corporate/press/042364 Suse evidently went with MariaDB and it was somewhat disconcerting to learn about the switch during an update. Has Arch considered what it will do in this situation, MariaDB?, MySQL? -- David C. Rankin, J.D.,P.E.

[arch-general] New device-mapper, lvm2 and cryptsetup packages in testing
by Thomas Bächler 03 May '10

03 May '10

I put updated device-mapper/lvm2 2.02.64 and cryptsetup 1.1.1-rc2 packages to testing. These packages enable udev synchronization to finally get rid of all race conditions related to udev rules. I also cleaned up the PKGBUILDs massively and removed all static binaries and libraries from the packages. Before cryptsetup can move to core, we obviously need to wait for the final 1.1.1 release, and libpopt, libgcrypt and libgpg-error need to move from /usr/lib to /lib, so that initscripts are able to open encryption even if /usr isn't available yet. Pleae give feedback on these packages.

[arch-general] kernel26-2.6.33.3-1, nut (upsd) is dead. It's either the kernel or nut 2.4.3
by David C. Rankin 03 May '10

03 May '10

Guys, After update to 2.6.33.3-1, network-ups-tools (nut/upsd) starts, but cannot communicate with itself on localhost or across the network anymore. The default abs configuration was used so it isn't with one of my famous configure strings. It starts fine, but then here is what I get in my logs: May 3 00:23:17 nirvana upsd[27067]: listening on 192.168.6.17 port 3493 May 3 00:23:17 nirvana upsd[27067]: listening on 127.0.0.1 port 3493 May 3 00:23:17 nirvana upsd[27068]: Startup successful May 3 00:23:17 nirvana upsmon[27070]: Startup successful May 3 00:23:17 nirvana upsmon[27072]: Communications with UPS archangel_ups(a)archangel.3111skyline.com lost May 3 00:23:17 nirvana wall[27074]: wall: user nut broadcasted 1 lines (70 chars) May 3 00:23:22 nirvana upsmon[27072]: UPS archangel_ups(a)archangel.3111skyline.com is unavailable May 3 00:23:22 nirvana upsmon[27072]: Communications with UPS nirvana_ups@localhost lost May 3 00:23:22 nirvana wall[27077]: wall: user nut broadcasted 1 lines (60 chars) May 3 00:23:22 nirvana wall[27079]: wall: user nut broadcasted 1 lines (52 chars) May 3 00:23:27 nirvana upsmon[27072]: UPS nirvana_ups@localhost is unavailable May 3 00:23:27 nirvana wall[27084]: wall: user nut broadcasted 1 lines (42 chars) May 3 00:28:23 nirvana upsmon[27072]: UPS archangel_ups(a)archangel.3111skyline.com is unavailable May 3 00:28:23 nirvana wall[27104]: wall: user nut broadcasted 1 lines (60 chars) May 3 00:28:28 nirvana upsmon[27072]: UPS nirvana_ups@localhost is unavailable May 3 00:28:28 nirvana wall[27108]: wall: user nut broadcasted 1 lines (42 chars) and every few minute or two, this gets dumped to the terminal: [00:25 nirvana:/home/david] # Broadcast message from nut (Mon May 3 00:28:23 2010): UPS archangel_ups(a)archangel.3111skyline.com is unavailable Broadcast message from nut (Mon May 3 00:28:28 2010): UPS nirvana_ups@localhost is unavailable and on the second Arch box [00:24 archangel:/home/david] # Broadcast message from nut (Mon May 3 00:28:41 2010): UPS archangel_ups@localhost is unavailable Broadcast message from nut (Mon May 3 00:28:41 2010): UPS nirvana_ups(a)nirvana.3111skyline.com is unavailable (I have two CyberPower AVRLCD 1000 ups'es that have always done fine. They use the usbhid-ups interface through /dev/hiddev0 and each monitor each other over the LAN. ) The abs package is network-ups-tools with abs updated and built against the nut-2.4.3.tar.gz source to make network-ups-tools-2.4.3-1-x86_64.pkg.tar.xz. To solve the problem, I dropped back to the abs network-ups-tools-2.4.1 PKGBUILD that I still had laying around and rebuilt against the new kernel and all is working as it should. So there is either a kernel error or error in the 2.4.3 nut package. Let me know if you want me to open a ticket. Thanks. -- David C. Rankin, J.D.,P.E.
