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 22.214.171.124 to find a safe place to start the bisect and had the coldboot segfault
(I'm not authorised to untick regression)
So the segfaults and XFS oddities only happen with CONFIG_IDE=n ?
I reassign that to the storage folks.
Re-assigning to the right folks for CONFIG_IDE=n.
Doubt its the right place but we shall see
Please build a kernel with 8K stacks and report if that behaves
