Linux crashes with PcktEngn GNIC-II/hamachi driver

ON: Intel i686, 266MHz, 64Meg Memory, 32bit PCI.
RedHat 5.2 Linux 2.0.36-7.
Switch is a Foundry BigIron B8GM card.

I am trying to bring up a Packet Engines G-NIC II card using
"hamachi.c:v0.07 8/17/98 Written by Donald Becker\n" 

On installation of the module the computer sees the card .  The switch sees
the card.  As soon as ifconfig is run, I get an immediate kernel panic without
any logged information about the problem.

I have tried changing max_interrupt_work to 10/40, and tried:

/*        writel(0x00080000, ioaddr + TxIntrCtrl);
        writel(0x00000020, ioaddr + RxIntrCtrl); */
        writel(0x00FF0000, ioaddr + TxIntrCtrl);
        writel(0x00FF0020, ioaddr + RxIntrCtrl);

perhaps as suggested in hamachi.txt.  All crash the same.  

As I have little idea what I am changing, I thought it might be a good time
to check in at the mailing list.  Any pointers are appreciated. 

Note: For all this, the node was configured with a dec tulip pci ethernet
card up and running as eth0.  I tried it without the tulip (physically
present in slot, but not configured and no tulip module installed) using the
distribution driver.  Still crashes.  All this hardware is new to us, so
there may be some really elementary mistakes happening.

Thanks for anything you can offer.

========== initial crash==========================
When I setup the card first time, I had the module installed, then plugged in
the fiber.  Got a "Too much work at interrupt".  Log:
