Subject: fail to boot btrfs rootfs

Date: Tue, 13 May 2014 11:35:04 +0800

Package: src:linux
Version: 3.14.2-1
Severity: important

Dear Maintainer,

After having upgraded to 3.14.2-1, system fails to boot with a btrfs 
root. It complains about unable to load btrfs.ko due to unknown symbols.

Comparing the depends of btrfs.ko in 3.13 and 3.14:
% sudo modinfo /lib/modules/3.13-1-amd64/kernel/fs/btrfs/btrfs.ko
filename:       /lib/modules/3.13-1-amd64/kernel/fs/btrfs/btrfs.ko
license:        GPL
alias:          devname:btrfs-control
alias:          char-major-10-234
alias:          fs-btrfs
depends:        libcrc32c,raid6_pq,xor
intree:         Y
vermagic:       3.13-1-amd64 SMP mod_unload modversions

% sudo modinfo /lib/modules/3.14-1-amd64/kernel/fs/btrfs/btrfs.ko
filename:       /lib/modules/3.14-1-amd64/kernel/fs/btrfs/btrfs.ko
license:        GPL
alias:          devname:btrfs-control
alias:          char-major-10-234
alias:          fs-btrfs
depends:        raid6_pq,xor
intree:         Y
vermagic:       3.14-1-amd64 SMP mod_unload modversions

By adding libcrc32c to /etc/initramfs-tools/modules, system boots again.

Regards,
Jesse
