First my apologies for sending an empty message of help to the list earlier
I was trying to obtain subscription info. :-)
Onto the problem:
I have a Dell Precision 220 with 256 megs of RDRAM. Non-ECC. The
220 is in a desktop case with a 230 watt power supply. The system
has a LSI-Logic dual channel SCSI host adapter with an ultra-160
SCSI 10K RPM drive. The graphics card is a Matrox dual head G450.
Two 866 Mhz PIII's (retail boxed processors) with the same stepping.
I am running FreeBSD 4.7. The kernel is configured to run SMP with
the only other option being a PCI sound device.
If I enable the second CPU I get SIGSEGV's on cc1 while building
emacs. Also when unzipping files or running gzip --test I get CRC
I can run the same gzip --test or try recompiling and it will work.
If the second CPU is disabled I never have any problem occur.
