2.6.15-rc2-ck2 with adaptive readahead: processes stuck in D state

2.6.15-rc2-ck2 with adaptive readahead: processes stuck in D state

[Frederik]

Today I compiled 2.6.15-rc2-ck2 kernel with adaptive readahead patch
v.8. The system is running Mandriva Cooker. With this kernel, it
occured two times to me, that urpmi --auto-select starts hanging, and
ps shows several processes stuck in D state (such as ldconfig).

I am using XFS for all file systems, I'm wondering if it is related to
this, because I see several XFS methods mentioned in the trace.

I have put dmesg, config and the trace online on
http://users.telenet.be/fhimpe/kernelbug/

I've cc'ed Wu on this reply. I should have made it clear that was the only way 
adaptive readahead feedback would be helpful.

Maybe it's this patch that solved the problem:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=551c81e2d32c5867fb592091365d8c37e1509dce
[XFS] Resolve the xlog_grant_log_space hang, revert inline to macro.

Cheers,
Wu

This is now fixed in Linus' git tree.
