I plugged a Promise UltraATA/100 card into my PC164 which has an NCR
53c810 SCSI controller & serial console (and has worked flawlessly for
more than 12 months), and 1.5_ALPHA2 panics with:
pciide0 at pci0 dev 6 function 0: Promise Ultra100/ATA Bus Master IDE
Accelerator (rev. 0x02)
pciide0: bus-master DMA support present
pciide0: primary channel configured to native-PCI mode
pciide0: using eb164 irq 0 for native-PCI interrupt
unexpected machine check:
mces = 0x1
vector = 0x660
param = 0xfffffc0000006060
pc = 0xfffffc00004c79f8
ra = 0xfffffc000031dd64
curproc = 0xfffffc0000564830
pid = 0, comm = swapper
panic: machine check
Stopped in swapper at cpu_Debugger+0x4: ret zero,(ra)
So, you're not the only one.
And to think I was going to make the Alpha into my server, because my
x86 box has started going flaky ...
