hi. I switched to [testing] to get gnome 3. I found that it was a pretty bad timing because I saw that pacman updated the kernel to 2.6.38 too, and the glibc, and nvidia drivers ! and gnome 3 all in one go. Oh my..; with gnome 3, I got the gnome-shell segfaulting quite often when I hit the left top corner. or bottom right corner. got log like Apr 8 19:02:34 soho kernel: gnome-shell[17340]: segfault at 938 ip b52aa518 sp bfcef0a0 error 4 in libnvidia-glcore.so.270.30[b4423000 +16b3000] in /var/log/messages.log and just during the last 30 minutes, all the pc gone "crazy": chromium stopped to respond. conky stopped to be refreshed. starting a new shell in a terminal worked but a rm on a file get stuck for no reason. I switched to a console and log in as root and never got a prompt. I had to hard reset (I lost no files: the journal has ben replayed fine) So I got call trace of chromium crashing in /var/log/messages.log but other soft too. This is a snippet of my /var/log/messages.log http://paste.pocoo.org/show/368742/ Is it a badblock on my /home (reiserfs) partition that produce that behavior ? I have done a reiserfsck and a badblock check on the /home partition and it found nothing. is it the kernel ? the libc ? I saw a convert process that segfaulted in libc ??
