Thanks for the advise !
About the memory test, i did that, 7 full passes, no errors, it's 512mb
ecc memory btw. I'm going to let it, when i go to sleep, run the whole
night.
hardware:
System is a dell precision workstation 650, dual xeon 2.4ghz w/HT, intel
E7505 motherboard.
distro: debian sarge
kernel: vanilla 2.6.14.5
for the rest there is nothing special to see in dmesg output, lspci or
with lsusb. cpuinfo shows everything what it should show.

Other findings;
- all kernels had the same issue, except (not 100 % sure) 2.4.2X kernels
- tried acpi=noirq without success and many many other acpi options &
combo's
- nvidia binary driver replaced by kernel nv driver but without success
I have no reason to suspect the tvcard which is a terratec value with a
bt878 chip, support in the kernel. But on the other hand it could be the
tvcard, but i see no relation to anything with it. I tried also using
DAC snoop in the bios but no good.
None of the issue's occur when using windows xp pro/rhel enterprise 4
I'm going to let the memory test on for the whole night, i'll also
compile the kernel with debugging options on. But i don't think the
debugging options will matter since nothing is logged when the freeze
occurs.
Greetz,
Mark
