With debug patch from comment #5.
Comment 7 Andi Kleen 2008-08-15 07:45:50 UTC 
What happened to the WARN_ON? Or does it not happen every boot?

I would like have wanted to see the WARN_ON in the log with the debug patch.

Comment 9 Jean Delvare 2008-08-15 07:49:39 UTC 
Oh, sorry. I patched kernel 2.6.26.1, not 2.6.27-rc3. I'll do it now, stay tuned.
