This is my first FreeBSD install on Alpha (though I've run it on i386 and sparc64 for years). I ran into rouble while trying to boot the install kernel. THis might be related to the thread I found at http://lists.freebsd.org/pipermail/freebsd-alpha/2005-August/002659.html ... at least, the symptoms seem similar to my uneducated-in-Alpha eye. Unfortunately, I don't have a serial console hooked up at the moment (it's in the wrong room to connect to my digiport and it's much too large to move up the stairs), so all of the following is tped in from my handwritten notes. After issuing a 'boot DKA600': ---------- FreeBSD/SMP: Multiprocessor system detected: 4 CPUs CPU0 (BSP): PAL ID: 0 CPU1 (AP): PAL ID: 1 CPU2 (AP): PAL ID: 2 CPU3 (AP): PAL ID: 3 t20: using interrupt typ1 on pci bus 0 t20: pcib0: on t20 eisab0: at device 2.0 on pci0 ---------- (Note that there are no EISA cards, just some PCI cards) The error then occurs, and looks like this: ---------- unexpected machine check: mces = 0x1 vector = 0x670 param = 0xfffffc0000006000 pc = 0xfffffc00003d49f0 ra = 0xfffffc00003d49d4 curproc = 0xfffffc0000912be0 pid = 0, comm = swapper [thread pid 0 tid 0] stopped at eisa_probe_slot+0x80: add s0,#01,s0 ---------- I notice that at this point I've been dumped to the db> debugger prompt, but the key mapping is messed up ... pressing 'g' gives me ',' for example. The output of 'show device' is: ---------- DKA0.0.0.2001.0 DKA0 Seagate ST32550W 9104 DKA600.6.0.2001.0 DKA600 RRD45 1645 DRA0.0.0.2007.0 DRA0 5 member RAID 5 DVA0.0.0.1000.0 DVA0 RX25/RX23 EWA0.0.0.2008.0 EWA0 (the MAC address) PKA0.7.0.2001.0 PKA0 SCSI Bus ID 7 PKB0.7.0.7.0 PKB0 SCSI Bus ID 7 R01 A12 ---------- The output of 'show FRU' doesn't include any errors. Aside from the network card and the video card, all the remaining PCI cards are SCSI adapters (including the one full-length DAC960 RAID controller). I did pull 2 additional SCSI adapter that weren't in use to reduce the device-related possibilities. Does this problem look familiar to anyone? What's the best way to approach an "unexpected machine check" error?
