[Kernel_Killer]

Now this is an interesting issue. If I go to mount a NFS share on a newly configured 4801, I get this:

kernel: integer divide fault trap, code=0
Stopped at mountnfs+0x80: idivl nfs_ticks,%eax
ddb>

Anyone ever seen this happen? The NFSCLIENT option is compiled into the kernel its using (Just in case someone was going to ask). TIA.

Not sure but at that point that's when I play ddb hangman :smile:

[Kernel_Killer]

Well, I thought it was hardware based, and threw some more hardware at it. Same problem. Here's the kernel I'm using.

Ok. Now it's getting weird. If you try to sftp to it, it also crashes the Soekris. SSH works fine though. I'm starting to widdle down the kernel a bit in hope to corner the issue.

[Kernel_Killer]

Ok. I did a brand new kernel, took out ALTQ, and uploaded to the Soekris. Now NFS mounts just fine without issue. Weird.

This tipped me off:


option ALTQ # ALTQ base
#option ALTQ_NOPCC # We don't have Pentium features on 486....
# NOPCC may be necessary if the Geode's TSC is really as buggy as it sounds
