First of all, https://wiki.edubuntu.org/KernelTeam/CrashdumpRecipe
wouldn't allow me to get any crash dump. It'd seem to get stuck in a
cycle. I don't know what the kexec'd kernel was supposed to do and after
it repeating the same actions twice (boot, apparent attempt to start X
(?), and restart of the cycle), when I saw zero disk activity for 1 min
or so I gave up.
Anyway, steps to reproduce:
* disable NetworkManager [might work with it, however my wireless network
dislikes NetworkManager]
* connect to the WPA-EAP wireless network with wpa_supplicant
* run Pidgin and enable Bonjour
* screen will turn black and freeze
* CAPS LOCK will start blinking
Running 'avahi-browse -rt _presence._tcp' doesn't trigger the crash.
Important notes:
* last time I got graphics corruption
* the kexec'd kernel while loading would fill the screen repeatedly with:
«[timestamp] iwl3945 <PCI IDs or sth> Microcode HW error detected.
Restarting.»
«[timestamp] iwl3945 <PCI IDs or sth> Microcode HW error detected.
Restarting.»
«[timestamp] iwl3945 <PCI IDs or sth> Microcode HW error detected.
Restarting.»
«[timestamp] iwl3945 <PCI IDs or sth> Microcode HW error detected.
Restarting.»
and so on.
If you wish I'll crash my system again happily (lol) but I'd like to
know what to expect from the kexec'd kernel & some more tips.
