I've run into a situation where, with heavy PCI bus traffic, freebsd 3.2
systems lock up. I havent tried it on 3.3 yet. The same scenarios do not
cause the problem on the exact machine in both FreeBSD 2.2.8 and LINUX so
it doesnt seem to be a hardware problem.
The problem can be duplicated regularly by passing 80Mb/s of traffic
through ethernet and serial devices and then doing a "find" to create
excessive disk access. The 2.2.8 and LINUX systems continue to run normally
while FreeBSD 3.2 hangs regularly.
I'll test this in 3.3 shortly...has anything been done in this area? It
seems to happen on passive backplace systems (although its more likely the
chipsets used on SBCs)...my acer MB doesnt lock up with the same test. This
problem has been duplicated on more than 1 system with completely different
hardware.
Any ideas?
