Hello.
I have noticed a complete crash (forced switch to console and Alt-SysRq-B doesn't work) when I use ath9k driver for my WiFi card. The problem is that the crash occurs after a few hours of use, so blind bissecting doesn't look like a short-term plan.
My card is (as lspci says):
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Subsystem: Device 1a3b:1089 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 17 Region 0: Memory at d7400000 (64-bit, non-prefetchable) [size=64K]
I use an Asus N53JN notebook, if that matters.
I have photos of two instances of the crash. The backtrace goes as follows (I typed this in, so maybe there is a typo somewhere - I hope there is none, though):
