Well, I guess nobody has really cared that alpha 8200s haven't worked since last September..... :-).... The following sys/alpha/clock.c revision is the culprit. The problem here, which, btw, the revision comments makes no mention of, is that there was a direct insertion if i8254 timer code into the alpha clock functions. Uh, the Alpha 8X00 doesn't *have* an i8254, and might not even have an EISA bus at all. This insertion is for clock calibration- not any of what the comments refer to. Quite hilarious, really. ---------------------------- revision 1.17 date: 2000/09/07 01:32:38; author: jasone; state: Exp; lines: +177 -29 Major update to the way synchronization is done in the kernel. Highlights include: * Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.) * Per-CPU idle processes. * Interrupts are run in their own separate kernel threads and can be preempted (i386 only).
