| |
I just had a play with an article from an old LinuxJournal, to see if I could set up a cryptoloop homedir on my Debian unstable box. Found making an fs on the loop device locks the kernel hard. (need reset button) When using loopback without crypto it all works fine.
Ayone else have the same experience?
Using util-linux 2.12, aes (same prob with twofish, blowfish).
Crash dump is attached, as is kernel config. When not running uml-switch, the crash still occurs but doesn't print the VM: messages. (I don't have a swap partition anyway, so what's that all about?)
