Rafael,

Sigh.....

Comment 3 Rafael J. Wysocki 2008-03-22 10:20:23 UTC 
I'll close the bug as unreproducible if it's not present in -rc7.
Comment 4 Markus Rehbach 2008-03-26 00:03:38 UTC 
2.6.25-rc5-git3 is oopsing but very seldom. 

Tried 2.6.25-rc6 with another harddisk and fs (xfs instead of reiserfs, debian lenny instead of suse 10.2). The rest of the hardware is the same. This combination of hard-/software works without problems.

-rc7 is out, I will test it with the old harddisk this evening.

Comment 9 Markus Rehbach 2008-03-28 00:28:36 UTC 
Linus wasn't really happy with this patch, I assume the following will go into mainline:

Will test and reopen the bug if necessary this evening.
Comment 10 Rafael J. Wysocki 2008-03-28 07:16:15 UTC 
Well, this has been merged already too, as

I think the bug is fixed for good now.
