Bug#624131: linux-image-2.6.39-rc4-686-pae: Can somewhat reliably produce kernel panic in btrfs code

[Maik Zumstrull <maik@zumstrull.net>]

Package: linux-image-2.6.39-rc4-686-pae
Version: 2.6.39~rc4-1~experimental.1
Severity: normal
Tags: experimental

By simply stressing the system with some I/O, I can make it crash within
seconds. I'm not setting a higher severity because the bug is in an
experimental file system in an experimental kernel.

Here's the important bits (by my guess) I have on screen from the kernel panic:

Bug at fs/btrfs/free-space-cache.c:1246
Bug type: invalid opcode: 0000
Kernel not tainted, running on an ASUSTek 1005HAG
EIP is at btrfs_add_free_space+0x285/0x39a [btrfs]
