rtc misses interrupts after resume

rtc misses interrupts after resume

[Wichert Akkerman]

I recently upgraded my laptop to 2.6.11.3 and removed the notsc boot
option I added a fairly long time ago to see if things worked properly
without it now. It seems to work, except that after a resume I get
an awful lot of these messages:

Mar 15 09:53:04 typhoon kernel: rtc: lost some interrupts at 1024Hz.
Mar 15 09:53:06 typhoon last message repeated 103 times

and indeed looking at /proc/interrupts interrupt 8 is not getting hit.

Can you add code to free_irq 8 before suspend and reacquire it after
resume? If it helps then we have some interrupt routing problems...
