Hi Andrew

Thank you very much for your reply.

We've certianly screwed around with the mmapping of IO space and such
things in recent months, and iirc 2.6.14 was somewhat in the middle of it
all.

Are you seeing the above problem on 2.6.16.x?


We used to see freezes more frequently (on both 2.6.16.18 and
2.6.14.2) before setting these tweaks:
- increase PCI latency of bttv device
- disable overlay on bttv driver
- enable HPET support for Character Devices
- disable "load DRI" in xorg.conf

After the tweaks, all 10 PCs have been under stress test for 48 hours,
and the first crash was on the 2.6.14.2. We will upgrade 3 more PCs to
2.6.16.18 today, to increase the probability of crashing on that
kernel.

Will keep you posted.

Regards
Keith
