I am on a fresh Arch install with linux 3.0.1-1, using the brcmsmac module. Initially, the wireless works for a few days. At some point, it will stop, outputing the following error repeatedly: Aug 7 09:55:27 localhost kernel: [ 825.796697] ieee80211 phy0: wl0: fifo 0: descriptor error Aug 7 09:55:27 localhost kernel: [ 825.796713] ieee80211 phy0: wl0: fatal error, re-initializing I can rmmod brcmsmac, reboot, shutdown, give it a few days, and start over and it will sometimes work. Other times, it will persist with the fifo errors. Please let me know you need additional log files. I had this problem since 2.6.38 and reinstalled Arch twice, thinking it was something with my setup that was done incorrectly but haven't been able to figure it out.

Not always, but more often than not. I am running 32-bit but have used 64bit prior. I reinstalled my system thinking that it was a problem with 64-bit libraries. The full lsmod is on the bug report. I am currently running fine again. I will keep my laptop on throughout the day in the hopes that it goes down. Let me know if you need anything else.

I noticed this issue is still pending. It is weird that the problem persists between cold reboots (which points to a hardware error) but is also dependent on the kernel version in use (which points to a software error). Would you happen to have additional cards to try ? Can you email a log file containing the 'fifo 0: descriptor error' bug ? Do you think that temperature has an effect on the bug occurring, does it make a difference if you let your machine cool down between reboots ? I identified an issue today that gives the same error message, but that issue only occurs on 64 bit platforms, and you report that you also see it on 32 bit platforms. Can you run a memory test on your system, e.g. one that tests the memory during an overnight test ? Reason is that the error message occurs because the DMA engine read invalid data from memory. Thanks, Roland.
