Title:
WiFi connection suddenly drops
Status in linux package in Ubuntu:
Expired
Bug description:
This started to happen only with newer kernel versions. The WiFi was
previously absolutely solid. When the WiFi connection drops, there
are clear kernel error messages:
Apr 08 22:39:29 konstantin kernel: iwl3945 0000:02:00.0: Queue 4 stuck for
2048 ms.
Apr 08 22:39:30 konstantin kernel: iwl3945 0000:02:00.0: On demand firmware
reload
Apr 08 22:39:30 konstantin kernel: ieee80211 phy0: Hardware restart was
requested
Apr 08 22:39:30 konstantin kernel: iwl3945 0000:02:00.0: BSM uCode
verification failed at addr 0x00003800+0
Apr 08 22:39:30 konstantin kernel: iwl3945 0000:02:00.0: Unable to set up
bootstrap uCode: -5
The last two messsages are repeated a few times. This is followed by
more detailed stack traces, but the hardware does not recover.
Unloading the iwl3945 module and reloading it did not help in a few
tests.
Looking at the log some more, I see this line
Apr 08 22:33:38 konstantin kernel: iwl3945 0000:02:00.0: Enabling
power save might cause firmware crashes
I will try to find out if this can be disabled and do more test then.
