At 8 MHz, my machine appears perfectly stable.
At 33 MHz, I get repeated trap type 12 panics.

What can be dependent on timing like this ?
If there are any suggestions as to where I can insert
debugging lines ?

I am not sure if this particular panic (trap type 12) holds all
the answers. The machine (at 33 MHz) has often done a
crash/reboot and wiped the errors off the screen.

Machine details:
386 clone (Blackship), no maths chip, 8M memory
ATI motherboard (ATI-386/B2-33, 64K cache)
AMI BIOS (04/09/90)
video: ET4000 based, DFI VG-5000 with 1 Mb
pc0 <color> at 0x60 irq1 on isa
com1 at 0x3f8 irq4 on isa
com2 at 0x2f8 irq3 on isa
wd0 (MAXTOR LXT-213A> at 0x1f0 irq 14 on isa
fd0 drives 0:1.2M, 1: 1.44M at 0x3f0 irq 6 drq2 on isa

Thanks for any advice
