bill webb in palo alto understands what's going on here, and offers the
following patch to ca/trap.c:
switch (mcs_pcs) {
+ case MCS_CHECK|USER:
+ case MCS_CHECK:
+ printf("spurious machine check ignored\n"sp);
+ return;
default:
if (mcs_pcs & MCS_CHECK) { /* machine check */
after seeing "spurious machine check ignored" printed a sufficient number
of times, you'll want to lose the printf and increment a counter.
