Prism 2.5 MiniPCI Wireless Unstable

[Michael B Allen <mba2000@ioplex.com>]

My wireless is a little fragile. I have a Thinkpad T30 with a MiniPCI card:

02:02.0 Network controller: Intersil Corporation Prism 2.5 Wavelan chipset (rev 01)
        Subsystem: Intel Corp. Wireless 802.11b MiniPCI Adapter
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at f8000000 (32-bit, prefetchable) [size=4K]
        Capabilities: [dc] Power Management version 2

If I run rsync it's guaranteed to get the kernel in a bad way. CPU goes to 100% doing what looks like an endless loop error handling. If I unload and load the orinoco, orinoco_pci, and hermes modules it restores normal behavior. But anything can trigger the problem. I just tried to print to a network printer and it triggered the problem. The first of many log messages follows:

Jul 11 00:03:07 quark kernel: eth1: Error -110 transmitting packet

Jul 11 00:03:09 quark kernel: eth1: Error -16 transmitting packet

I tried changing irqs around a while back but I can't see any difference. Is there anything I can do about this? I had problems with 2.4 using the hostap driver too but it was stable enough to run my rsync backup. I'm systems programmer and I'm willing to patch & debug.

Thanks,
Mike
