general, but I can say the first step is to compile a kernel with
DIAGNOSTIC and DDB enabled in the config, and also add "options
IWN_DEBUG". With IWN_DEBUG it may actually print something when the
problem happens, which would obviously help a lot.
Adding options IWN_DEBUG produces
../../../../dev/pci/if_iwn.c:190:1: error: "IWN_DEBUG" redefined
during make depend.
IWN_DEBUG is already #define'ed in if_iwn.c, but the variable iwn_debug is set to 0. Looks like the right thing is to set it non-zero, e.g., to 5 for the maximum amount of chatter, by changing line 195 to
int iwn_debug = 5;
I will give this a try.
