Hi managers. Sorry for the late summary, but I wanted to make sure I had the
problem solved. I also wanted to give Sun time to come out and take a look.
The original question is at the end. First off, thanks to the following:
herman@ct.med.ge.com (Scott R. Herman)
Peter Polasek <pete@cobra.brass.com>
Frank Cusack <fcusack@voicenet.com>
poffen@San-Jose.ate.slb.com (Russ Poffenberger)
Most of the suggestions were to check the permissions on ps, /dev/mem, and
/vmunix. Those were ok. What ended up fixing the problem was reinstalling the
OS.
Original question:
> Hi managers. I have an old IPC running 4.1.4. When running any of the above
> commands, it gives the following error:
> /dev/mem: error on kas: Bad address
>
> ps also gives the following error:
> ps: could not read kernel VM
>
> I looked at a previous summary which indicated this error means that the
> kernel image in memory is not the same as /vmunix on disk. However, I don't
> think this is the case this time. I've rebuilt a couple of different kernels,
> and they all compiled without errors and booted up fine. I've also checked the
> eeprom settings to make sure it really is using /vmunix to boot up with, and

> boot-from=sd(0,0,0)vmunix

> My memory of these older architectures is a bit rusty, but I think that's an

> Is there anything else to check that I'm overlooking?
