Dear Hans,
I reported these issues a few months ago with ivtv tip and an earlier
kernel, and you suspected it was hrtimer related, but I have built
kernels with hi res disabled, it still seems to be an integral part of
the kernel, and still appearing in the traces. This is a build from
2.6.24-rc3. There is multiple cards installed in this machine. I shall
supply more traces as the crashes happen from different machines.
I have two crashes here, one a panic, and one a lockup, that kept
repeating printing every 11seconds, identically.
# CONFIG_HIGH_RES_TIMERS is not set
Thanks for your help
Regards,
Mark Bryars
