Subject: [Bug 14354] Bad corruption with 2.6.32-rc1 and upwards
http://bugzilla.kernel.org/show_bug.cgi?id=14354
--- Comment #117 from Linus Torvalds <torvalds@...ux-foundation.org> 2009-10-26 15:42:41 ---
Just a note: I'm seeing this too on my new Dell laptop, with a fresh
Fedora-12 Beta install (+ "yum update" + current -git kernel).
The root filesystem was seriously scrogged, and I had the RPM databases
corrupted. Don't know what else is wrong, I'm rebuilding them now.
I had a few unclean shutdowns (debugging wireless driver etc), but they
weren't during any heavy disk activity. And I'm pretty sure they weren't
during any yum update, so the rpm database corruption smells like ext4 is
not writing back inode information in a timely manner at all (ie any rpm
database activity would have happened much earlier).
Example kernel messages appended. I probably missed a few. I do not have
fsck logs (this was all on the root filesystem, nowhere to log them), but
they weren't pretty.
I can do pretty much anything to this laptop (I'm just testing it), so I'm
open to testing.
