Subject: General protection fault with aborted ircomm FIR connection
Date: Wed, 30 Aug 2006 01:15:34 +0200 [thread overview]
Message-ID: <44F4CA96.6060607@gmx.net> (raw)
Hi,
first of all, no proprietary modules have ever been loaded. The "Tainted"
refers to "SUSE unsupported" modules. Machine is a Samsung P35 laptop (x86).
Kernel is 2.6.16.21 with SUSE patches (which don't touch IRDA afaics).
FIR chipset is served by nsc-ircc dongle_id=0x08.
The crash happened when I used gammu to connect to my nokia mobile phone
over /dev/ircomm0. I moved the phone out of the IR beam by accident and
then killed gammu with Ctrl-C while it still had the connection open.
At that moment, the kernel spewed a general protection fault on me.
