SubjectRe: encrypted swap on loop in 2.4.10-pre12?
From
Date
agreed.  i've had this problem on two seperate systems, however i _am_
running a few other patches- notably the kpreempt patch. but again, no
problems at all until 2.4.10-pre12. i'll try some things in the morning
and see what i can come up with. i see you are doing swapon, however
have you tried mkswap over your loopdev? i can actually swapon just
fine, its mkswap that causes the panic.
