panic (cpu: 0) Unaligned kernel space access from kernel mode
I have an Alphaserver 4100 and after an temperature site problem the server is sending this message:
Loading vmunix symbol table ..┬┤.[1239992]
Unaligned kernel access va 0xfffffc00070b932 pc=0xfffffc4c0
panic (cpu 0)Unaligned space access from kernel mode
DUMP: No primary swap, no explicit dumpdev,Nowhere to put header, giving up.
Thanks in advance
Victor

Re: panic (cpu: 0) Unaligned kernel space access from kernel mode
you should define dump_dev on console prompt to a partition, the machine can dump to.
greetings,
Michael

Re: panic (cpu: 0) Unaligned kernel space access from kernel mode
it would surprise me if it detected the dump at all except in a dump space. You would corrupt most certainly any file system if the os didn't prevent if with an open device error in the first place. The dump_dev is the location the os dumps it if does not proceed beyond the definition of swap in sysconfgigtab.
HP, am I correct?
Michael

Re: panic (cpu: 0) Unaligned kernel space access from kernel mode
Victor - have you tried booting from either the generic kernel or the installation CD and see what you can see as far as disk devices go from the OS?

Re: panic (cpu: 0) Unaligned kernel space access from kernel mode
As far as the panic, I would recommend re-running the ECU (EISA Configuration Utility) from floppy at the console level. All you need to do is run it, then save/exit and power cycle the system. I have seen several similar problems caused by a 4100 losing the EISA configuration information stored in NVRAM.

Martin

Re: panic (cpu: 0) Unaligned kernel space access from kernel mode
For some reason my ECU floppy does├В┬┤t run, but I will try to get some other, but the question is if I have to run it considering that I don├В┬┤t have any EISA option, the server has only SCSI controller?
