>Description:
I have an IBM Thinkpad R40, and FreeBSD hardware support has been outstanding for everything but my Cisco MPI350 wireless card. At first, wireless would either quit or lock up entirely, sometimes with strange kernel messages, sometimes with no warning at all.  So, I went into the BIOS and changed the INTC irq to 9 (INTC seems to control the irqs of my wireless and uhci2). Ever since I gave an0 a unique irq (shared only with uhci2), the wireless has worked perfectly, until I plug in a USB device.  When I plug in a USB mouse, I either have a solid lock-up of the system, or I get the following repeatedly:

an0: failed to read RID ff50 7f00 2 3fe 0, 3
an0: failed to read RID ff50 7f00 2 3fe 0, 3
an0: failed to read RID ff50 4a0c 230b 3fe 0, 3

After a short time, ifconfig reports the status of an0 as "no carrier".

I have also run Linux 2.6.7 and Windows XP on here with complete success, but FreeBSD 4.x and 5.x have issues with my irq setup.  Even setting the BIOS irq settings to "Auto" doesn't solve the problem, and in fact makes it worse (guaranteed lock-ups, since the Cisco card is sharing an irq with a system-critical device).

I would be happy to submit any information you may need!  I'm sure it would also help if I told you that in 4.10 GENERIC I was getting "stray irq 7", which was my parallel port, even when the port was disabled in the BIOS.  Now that I've changed irqs, I can't even use the parallel port at all (ppc0: cannot reserve I/O port range), but I'm sure more BIOS fiddling would change that, this is still annoying.  Below is a sample dmesg output. As you will notice, I was hot-plugging a USB mouse into my USB ports to see if a problem would arise, and then I'd try to reinsert the if_an module. Thanks for your time!

>How-To-Repeat:
      Use the Cisco card in conjunction with a device sharing its irq.
>Fix:
      Don't use a device using the same irq as the wireless card.
