OK, hrtimers are disabled on your system, but we still announce
the usec clock resolution to userspace, which is used by HTB to
calculate the burst rate. But actually that can't be the reason
since that has already been the case in 2.6.22. Please post a diff
of the bootlog from 2.6.22 and 2.6.23.

Any possible relation to clock source? logs seem to indicate acpi
source; how does tsc or jiffies do?

BTW, I could be wrong about this, but iirc in a xeon i had access to i
saw that i could not guarantee the same clock source would be selected
across reboots in about 2.6.22.

cheers,

Patch applied. Rebooted over kexec to 2.6.23 without nmi_watchdog, for now 
all seems fine.
