That might be an lfence instruction.  I suspect you've chosen the wrong
CPU type?

Gee, you guys are good. Now I'm only left wondering how this setting could be
reset to PIV, while I'm sure I set it to PII (as you can see from earlier
postings, I managed to get it running till a SCSI lockup caused by probably
IRQ prioblems). For now I'll not blame the kernel and tell myself I'm stupid
;-)

Which SCSI? I've been seeing numerous aic7xxx badnesses ca. whatever bk
snapshot 2.5.65-mm2 was based on. Still looking for the use-after-free...

00:06.0 SCSI storage controller: Adaptec AIC-7880U

Onboard SCSI controller, MPS 1.4 enabled Intel 440 LX chipset (i.e. IRQ
rerouting and stuff) Kernel is recompiled now (processor type change takes a
while, for you need to recompile everything from scatch) to test the
different IRQ settings, have dealt with problems like these before.

Note that I'm testing the official,plain Linus-2.5.65
