Hi guys, - bump to latest version

greetings tpowa

tpowa I am seeing a kernel bug with 2.6.37.3-1. I can't read these things, but here is what I got:

This is Arch i686 running as a guest in the latest virtualbox. This crash seems to occur when you try any type of I/O that goes out of the machine. Like rsync or trying to access one of the shared folders.

I downgraded the guest VM to -2.6.37.2-1 and the problem is gone. Let me know what other information you want to see.

I have also seen some strange behavior in x86_64 dmraid. I thought it might be a disk problem, but it started about the time of the kernel upgrade as well.

Cheers.

Same issue on x86_64 on vbox: /var/cache/pacman/pkg/kernel26-2.6.37.3-1-x86_64.pkg.tar.xz Trying to access anything outside vbox results in the following: Mar 12 21:00:35 localhost kernel: ------------[ cut here ]------------ Mar 12 21:00:35 localhost kernel: WARNING: at fs/inode.c:860 unlock_new_inode+0x45/0x50() Mar 12 21:00:35 localhost kernel: Hardware name: VirtualBox Mar 12 21:00:35 localhost kernel: Modules linked in: ipv6 vboxvideo drm vboxsf ext2 joydev usbhid hid snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device ohci_hcd snd_pcm_oss snd_intel8x0 snd_ac97_codec ac97_bus snd_pcm lp snd_mixer_oss ppdev ehci_hcd tpm_tis snd_timer tpm snd tpm_bios parport_pc usbcore i2c_piix4 sg soundcore button processor ac snd_page_alloc e1000 vboxguest psmouse evdev pcspkr parport serio_raw i2c_core ext3 jbd mbcache sd_mod sr_mod cdrom ahci ata_piix libahci pata_acpi libata scsi_mod Mar 12 21:00:35 localhost kernel: Pid: 1094, comm: bash Tainted: G W 2.6.37-ARCH #1 Mar 12 21:00:35 localhost kernel: Call Trace: Mar 12 21:00:35 localhost kernel: [<ffffffff81056a1a>] warn_slowpath_common+0x7a/0xb0 Mar 12 21:00:35 localhost kernel: [<ffffffff81056a65>] warn_slowpath_null+0x15/0x20 Mar 12 21:00:35 localhost kernel: [<ffffffff8114c465>] unlock_new_inode+0x45/0x50 Mar 12 21:00:35 localhost kernel: [<ffffffffa03a3c18>] sf_lookup+0x218/0x2c0 [vboxsf] Mar 12 21:00:35 localhost kernel: [<ffffffff81140487>] d_alloc_and_lookup+0x47/0x90 Mar 12 21:00:35 localhost kernel: [<ffffffff8114b6f0>] ?
