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

["Adi" <adalbert.b@gmx.de>]

ok, i have tried the 2.6.35-rc6 kernel, as TiCPU on #btrfs suggested, b=
ut i also got an error. i don't think it has something to do with kcryp=
t, as i can mount another partition without any problems.

hm, and btw, that dump was made on another pc.

here is a dmesg-dump:
