This entry is being used for tracking a regression from 2.6.26.  Please don't
close it until the problem is fixed in the mainline.

It turns out I made a config change - I had a problem recently with a CDROM drive and I was pointed at the libata pata drivers. So I did CONFIG_IDE=n

When I do CONFIG_HAVE_IDE=y the segfault on coldboot no longer seems to be appearing on 2.6.27-rc4

It's not a regression though - I went back to  2.6.25.14 to find a safe place to start the bisect and had the coldboot segfault
(I'm not authorised to untick regression)
Comment 2 Thomas Gleixner 2008-09-04 14:19:02 UTC
So the segfaults and XFS oddities only happen with CONFIG_IDE=n ?

I reassign that to the storage folks.
Comment 3 Bartlomiej Zolnierkiewicz 2008-09-04 15:39:34 UTC
Re-assigning to the right folks for CONFIG_IDE=n.
Comment 4 Alan 2008-09-04 16:35:09 UTC
Doubt its the right place but we shall see

Please build a kernel with 8K stacks and report if that behaves
