Comment 51 for bug 37773

I have a desktop system (AMD64 on an ABit AV8) which has an atheros chipset (pci id 168c:0013) and it works completely reliably, the machine simply never crashes.
However, I have just also acquited a Thinkpad x40 with the atheros chipset and I have seen a few crashes where the whole system hung. I'm running network-manager on it and I don't notice any particular link between anything and the crashes, but SysRq does still work. Next time I will try and get a dump out of it, but usually it crashes while I'm in X and all I can do is alt-sysrq-b
