Subject: Re: Kernel (2.6.24) crash on nfsd (BUG: soft lockup)
Date: Thu, 28 Feb 2008 12:08:52 +0100	[thread overview]

Over the past few days, our fileserver has crashed with this bug a 
couple of times. We downgraded the kernel to 2.6.23.17 last night, but 
about an hour ago the machine crashed again, this time with a sligthly 
different stacktrace (attached).
This is driving us nuts: kernel 2.6.17 to 2.6.22 are not possible, 
because of the lockd issue, and 2.6.23 and 2.6.24 are not possible 
because it crashes even more often.

I noticed that Rune Nilssen reported the same issue a few days ago to 
this list, but he too hasn't received any response yet 
(http://article.gmane.org/gmane.linux.nfs/19105).

Any more people here that suffer from this issue? Can I get/give more 
information to make debugging easier?
