Cisco Aironet MPI350 freezes on 5.2.1-RELEASE (IBM T30)

[Duane Winner]

Hello,

I have an IBM T30 (2366-81U) with a Cisco Aironet MPI350 mini-PCI 
adapter (an0). Running FreeBSD 5.2.1-RELEASE p8.

The card has firmware 5.00.03

I have been able to use this card with little problems on 4.9-RELEASE, 
but now that I've installed 5.2.1, I have been getting disturbing lockups.

I noticed it yesterday while I was doing a "portinstall mutt". Three 
times it attepted to download the source tarball, and it would get 
anywhere fro 30-80% and my entire machine would just freeze, and I would 
have to do a cold restart. Going into X and using Mozilla, I would 
sporadically get the same problem.

I know this was a problem before, and people have reported this problem 
when the MPI350 had the newer firmware, but downgrading the firmware to 
5.00.003 always seemd to cure the problem.

The other thing is that 'dmesg' produces no error output in regards to 
the 'an0' device, so I'm not even seeing any errors. The machine just 
freezes.

This is all the dmesg information I get:
an0: <Cisco Aironet MPI350> port 0x8000-0x80ff mem 
0xd0400000-0xd07fffff,0xd0200000-0xd0203fff irq 11 at device 2.0 on pci2
an0: got RSSI <-> dBM map
an0: Ethernet address: 00:02:8a:df:74:c4
an0: supported rates: 1Mbps 2Mbps 5.5Mbps 11Mbps

Any advice or help would be greatly apprectiated.

Thanks,
Duane Winner
