Recently I came across two more things, that are possibly related to
IO-APIC problems:
1)http://xfree86.org/pipermail/xpert/2001January/004751.html
Someone with SMP that has problem with interrupt delivery (stuck
interrupt). Only in SMP mode and this is not NE2000 related.
2)http://developer.intel.com/software/idap/media/pdf/copy.pdf ( Page 8

It turns out, that there's an errata in early Pentium III revisions,
that could corrupt data written to IO-APIC. ( Only if SSE write is
followed by an APIC write)
