I believe 2609 describes a regression in 1.0.13. It is very easy to recreate when jfs.o is built as a module. A fix for 2609 is in drop 1.0.14 which we're working on today. > > I would like to have some hints how to isolate the problem.

For me it looks like some kind of deadlock in jfs. I find kgdb very useful. It requires two machines to be connected via a null-modem serial cable.

I'm guessing this has to do with fsck.jfs using an ioctl, BLKSSZGET. This is new to fsck.jfs, but it seems the md driver doesn't like it. You can probably ignore it for now and we'll figure out what fsck.jfs should be using. > > Reference: > Bug 2591: http://www- > 124.ibm.com/developerworks/bugs/?func=detailbug&bug_id=2591&group_id=35 > Bug 2609: http://www- > 124.ibm.com/developerworks/bugs/?func=detailbug&bug_id=2609&group_id=35 > > Please resond to [EMAIL PROTECTED], the subscribe does not seem to work, > i tried it 15 hours ago and did not get a mail.
