[yellowfin] Hamachi Kernel Panic on 2.4.9

[Chris Tracy]

I'm attempting to move my firewall to 2.4.x from 2.2.x and don't seem to
be having much luck.  After swapping out my Tigon-I based 3c985 for a
GNIC-II, I find myself unable to see or send any traffic on the GNIC-II
using the drivers in 2.4.9-ac5.  Furthermore,  after about 5 minutes of
attempting to use the card, I get the following kernel panic:

  <0>Kernel Panic: Aiee, killing interrupt handler!
in interrupt handler - not syncing

	It's an SMP box running 2 PIII 600MHz on a SuperMicro P6GDU with
512MB of RAM. It runs 2 disks (both 9.1GB SCSI) off it's internal aic7xxx
controller.  Besides the GNIC-II, it has a 3c985B-SX and a 3c905C.  The
panic occurs with and without the 3Com modules (3c59x and acenic) loaded.

	Hamachi init looks like:

hamachi.c:v1.01+LK1.0.1 5/18/2001 Written by Donal Becker
	Some modifications by Eric kasten <kasten@nscl.msu.edu>
	Further modifications byt Keith Underwood <keithu@parl.clemson.edu>
eth1: Hamachi GNIC-II type 10911 at 0xe0c51000, 00:e0:b1:04:16:d3, IRQ 9.
eth1:  32-bit 33MHz PCI bus (60), Virtual Jumpers 30, LPA 0000.

	It's been a long night, and I'm rather tired at this point, so if
I'm leaving something out, let me know.
