Apart from the timer drift thingie, 2.6.10 brought some new features
like usb devices (ramdomly) not working after resuming from suspend mode.
In 2.6.9 usb worked well, resuming from suspend just throws a bunch
(near 20) messages like:
drivers/usb/input/hid-core.c: input irq status -84 received
(getting form /var/log/syslog, just don't have time to switch back to
2.6.9 and fiddle with it again). After those messages, the usb subsystem
comes stable again and worked like a charm.
In 2.6.10, resuming from suspend mode just (randomly) crashes the USB
subsystem, and I get the same messages (not sure about the whole message
but the "-84" part really is there) over and over again until I reboot.

Same problem here.
For me, the work around was to remove the uhci-hcd before suspending and
inserting it after resuming.

Does it still happen with noapic? 2.6.10 has some interrupt related
problems with APIC...

I have just rebooted 2.6.10 with this LILO command line
LILO Boot: Linux-2.6.10 noapic
and if that disables APIC, then I've got the same problem. After
suspending the laptop
two times, I get the same lines (described below) and the usb system
goes nuts. After
removing & inserting uhci_hcd everything works fine again.
The lines are (endless loop):
drivers/usb/input/hid-core.c: input irq status -84 received

I guess you need to ask on usb lists. If removing/inserting uhci_hcd
helps, it is likely that uhci_hcd needs to do a bit more in its
suspend/resume callbacks.
