Ok, now that dumpd{ev,ir} have been set up, vmcore is available if
somebody serious wants to look; backtraces (in text form) are
available (I did not know what else to look for) ...
First debug trace (happens to contain dmesg too):
http://www103.pair.com/parv/comp/unix/freebsd/thinkpad-t42-2373-5tu/err/2007-04-19.ath-lor/00-crash/kern-debug.log
Trace generated after "ifconfig ath0 mode 11g":
http://www103.pair.com/parv/comp/unix/freebsd/thinkpad-t42-2373-5tu/err/2007-04-19.ath-lor/00-crash/kern-debug.ath-ifconfig-mode11g
... seems almost the same, those two, save for dmesg in one.
Please let me know if you would like to see anything not already
presented.
While fiddling, I found that ath0 driver has been giving trouble
since yesterday evening if try to set "mode 11g" either in
/etc/rc.conf or manually via ifconfig.
Just what the hell could have changed suddenly -- most likely on
Linksys WRT54g v4 wireless AP/switch/router as I do not remember
changing anything (world|kernel wise) on this FreeBSD Thinkpad T-42?
(Yes, the internet connection from Comcast, at home, to sites on
pair.com was terrible.)
