tmm e330758d56 Completely disable interrupts (not just raise %pil) when calculating the ... value to be written into tick_compare in tick_hardclock(). While we were taking care that the value to be written was at least TICK_GRACE ticks in the future, a vector interrupt could happen between calculating the value and writing it. If it took longer than TICK_GRACE to complete (which is doubtful for a single device-triggered vector interrupt, but quite likely for some IPIs), the value written would be in the past and tick interrupts (which drive hardclock and statclock) would stop until %tick wraps around, which takes a long time. Also, increase TICK_GRACE from 1000 to 10000 for good measure. Reported by: kris Reviewed by: jake Approved by: re (scottl)		2003-05-29 17:49:21 +00:00
