Re: wanted X found X-1 but you got X-2

hi,

i used a current stable gentoo with a 2.6.34-r2 gentoo-kernel. the btrfs filesystem is on a lvm, which is on a luks-partition.
i think i corrupted the filesystem with a 2.6.34 tuxonice kernel, witch ran fine without suspend-to-disk, but after suspending i couldn't reboot anymore.
this debug is made on a sysrescuecd 1.5.8, after i try to btrfsck it. if i try to mount it, the terminal hangs, but i can switch to another.
would it help if i copy some data off the filesystem?

ciao, adi
