Bug 140948 – suspend2-sources-2.6.17-r2 oopses with reiserfs on a loopback device

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Lukas Sandström 2006-07-18 11:16:32 UTC]

I created a 800Mb file and created a reiserfs-filsystem on it:
 dd if=/dev/zero of=file bs=1M count=800
 modprobe loop
 losetup /dev/loop0 file
 mkreiserfs -b 512 /dev/loop0
 mount /dev/loop0 /mnt/hd -t reiserfs

If I leave out the "-t reiserfs" mount causes a floating point exception
at this point.

Then I tried to mv /usr/portage to /mnt/hd, except the distfiles.
After a while mv caused an oops.

Unsupported kernel. Reopen if you can reproduce w/ latest gentoo/vanilla sources.
