Public bug reported: I have RT2800-based 5 GHz wireless card that serves as access point with hostapd. The hardware has served me well for years, but just yesterday on the 6th, the system has started crashing random. The system is headless, so I have no images of the prior crashes, but I connected up LCD last night and when I woke up, I saw a crash on the screen which I photographed. None of the crashes seem to be logged in dmesg. Based on experience so far, the system crashes unpredictably, the shortest interval that I've seen it crash is 20 minutes and the longest may be about 10 hours. Typically it won't last more than an hour, though.
I found Tuomas Räsänen complaining about a crash that smells like the same issue to me: http://permalink.gmane.org/gmane.linux.drivers.rt2x00.user/2460 Tuomas mentions that the crash occurs on hostapd version 2.x only. According to my dpkg.log, hostapd updated from version 1:1.0-3ubuntu4 to 1:2.1.0ubuntu1 on 6th 09:00, and the first hard crash was sometime between 18:18 and 19:20 that day. I am currently running with rt2800pci removed from kernel, which seems to have worked around the crash. My other wlan card, ath9k, seems to produce no problems.
