It appears that the intel Se7501BR mother is also having
issues with ACPI. When ACPI support is enable the e1000
controller stops working printing "<6>NETDEV WATCHDOG:
eth0: transmit timed out".
Must...have...interrupts.
You are 100% correct.
That said... I'm tempted to extend NAPI just a bit, to provide an
"always poll" mode. It seems like all the bug reports I get these days
for 8139too are caused by x86 ACPI/APIC/irq routing troubles completely
unrelated to the driver. Tulip-almost-NAPI in 2.4 has an always-poll
mode, so I have a convenient excuse :)
