wild pointer bootup problem

[mdg]

I'm running 8.1 stable on an old presario 700z laptop.

Have the following strange behavior: Exactly every other time that I bootup from my HD and from power down I get the message

panic: zfree(0x14beaef0,48); wild pointer

This only seems to happen when I boot from my HD. I can repeatedly boot from a disk or floppy without this problem, but if I just booted from my HD and then do a power down and then try to boot from a disk or floppy, it will not boot and I have to power down again to reboot.

Any ideas as to what I can do to correct this problem. My BIOS setup is very limited as to what I can set.

Looks like bad memory in DMA that is why only power down works and reboot does not.

Actually, reboot works. It is power down that gives the problem - exactly
every other time.
