SS2 crashing with 'Memory address alignment' error

2007-12-25 7:45:00

   In response to my message about sparc Station 2 crashing

with the error: Memory address alignment, I got 2 suggestions:

- perhaps you have 1MEG SIMMS in lower Memory

  banks than your 4MEG SIMMS, the 4MEG SIMMS *MUST* be in the lower

  numbered banks.

- A bad memory simm. Take out the CPU board and reseat the simms.

  or try replacing them one at a time until it no longer crashes.

 On the error panic: swap_xlate

I got one response from pwh@bradley.bradley.EDU :

   We are trying to find a bad memory simm but have yet to locate it.

We do not have a third party SCSI driver so that suggestion was ruled

out.
