Regression? 2.6.27-rc3 segfault on cold boot; not on warm boot.

Regression? 2.6.27-rc3 segfault on cold boot; not on warm boot.

[David Greaves]

I have a desktop system that has started having problems booting up in the morning.

It appears to just happen on more recent kernels.
I was having unrelated CDROM problems with a driver in an old kernel and decided
to test 2.6.27-rcX
The CDROM problem is fine now.

However I started having problems on -rc1. I found that the machine was hanging
soon after booting and needed a reboot. After a reboot it would work fine for
the rest of the day.
When -rc3 came out I tried that and the problem still appears to be there.

The normal process is now to boot to single-user, ctrl-alt-sysreq-SUB and then
reboot to multi-user. This isn't ideal.


If I cold boot 2.6.25.3 the problem doesn't occur.
I will try different versions over the next few days.

Sample log from a few days back. (2.6.27-rc1 I think)

The problem does cause filesystem crashes so I'm cautious about messing around
unguided.

Happy to try any suggestions.

David
PS I've run memtest and it's fine.

Please try 2.6.26.x and see if the problem is present in there.

I'm pretty sure it is - it's my wife's machine and she's been stable on 2.6.25
for a while. I moved to 2.6.26 to fix a CDROM problem and I think that was when
I encountered this. IIRC I then tried 2.6.27-rcX to see if it had been fixed and
here we are...

I'll confirm tomorrow morning.

I wrote first in case there was any debug/instrumentation worth configuring in
as I have plenty time to recompile a kernel before shutting down tonight.

[The issue is probably present in 2.6.26 too]

As promised, I tried 2.6.26.3 this morning and didn't have the problem. I will
try again a few times to confirm.
Nb Although the log had an XFS failure, I think the real issue is the segfaults;
I think XFS is a casuality, not a cause. Th problem almost always results in an
XFS crash at some point - but usually preceded by many segfaults in random binaries.

Yes, below is a netconsole boot of 2.26.6.3

I cold booted - lots of segfaults. I then did a ctrl-Alt-SysRq-S-U-B to a warm
boot. No segfaults
(lots of #### mark the split)

I've just started 2.6.25.14 building for tomorrow to confirm how far back it
goes. (I'm 99% sure 2.6.25 is OK)
