| |
Hello All,
The following report applies to 2.6.39.3 (vanilla code). I also see it consistently on 2.6.39.2 and 2.6.38-gentoo-r6.
I am trying to switch to using the in-kernel modules for my remote control and vfd display needs. I have built the kernel with the mceusb module for the MCE remote that I use to control the machine and the imon module to provide an LCD interface for lcdproc (I don't use that actual remote). There's also another, unused, remote interface on one of my DVB cards (rc_winfast module). Kernel modules for the MCE and other remote load fine.
Attempting to load the imon module crashes Linux hard (no recovery other than hard reset). Details are below. It seems to be related to keytables. The iMon device is an older VFD device in a Silverstone case, with mouse control on the remote, no volume knob. Details of the iMon USB device are below the crash details.
I hope this is a dumb mistake on my part. I would appreciate any assistance. Regards, Chris
root@kepler # modprobe -v imon debug=1 (I have also tried specifying display_type=1)
