To work around this in the short term you can use this patch, in
addition to the clocksource watchdog patch that Thomas brewed up.

I pick that up as is. It's a non issue for KGDB=n

Comments are welcome of course.  Ultimately the right solution is to
change separation between the console and the HW to have a polled
mode + work queue so as not to introduce any kind of latency.

Care to take a stab ?

Thanks,
