1) After a few days of normal usage (with quite a bit of suspend and
resume cycles) this error was again triggered. So avoiding
check_plcp_health() doesn't seem to help.

2) I never send you the debug output (ie, output after doing "modprobe
iwl4965 debug=0x47ffffff"), did I?

No, but if error show up after few days, gathering and analyzing few
days of debug logs in impractical.

I see.

Does wifi stop working after an
error, or there is some other negative impact? Or only that messages
are printed and driver recover itself?

There doesn't seem to be any impact (ie, it might have some impact but
I'm too insensitive to notice). The driver does recover itself and I do
not have to mess with rfkill or "modprobe -r" or whatever. I actually
discovered this because I tend to regularly do
    dmesg -r |  grep "^<[123]>"

to keep myself informed of any kernel errors (or worse). And then these
few dozen lines can't go unnoticed.
