Backout rev 1.218 of src/sys/i386/isa/clock.c so the irq0 interrupt # # handler is reactivated and the RTC fiddled. # # Will do so next. I've nailed the change between March 6 and March 30. # 1.218 is from 2005/03/24 21:34:16, which would fit. We have a winner. Backing out 1.218 from a 2005/03/24 system does the trick, as well as a CURRENT without 1.218 (but 1.219-220 in there) bring back irq0 and time dilation is gone. All clocks work correctly. Now the question is: what is so special in my system so that I appear to be the only one to notice the problem?
