Hi All,

I have been scouring this list (and others) for solutions to several
problems I have encountered, with much success. I now have the cxm
drivers installed and working (?). I installed the latest MythTV
sources (as of yesterday, rev 13117) and applied the lock-fix.diff
patch (thanks usleep!). The only problem I'm having is that if I start
reading from the cxm driver for more than say 30 seconds (it seems
quite random), my computer reboots. It doesnt freeze and then reboot
after a bit, it just reboots immediately.

I think the problem may be the "tuner code" that I have added to the
cxm_eeprom.c file. My tuner code is 0x5c. I looked up in the ivtv
sources and they point to Philips FQ1236A MK4, which is no where to be
found in the current cxm_eeprom.c. I tried some of the other Philips
tuners, to no avail, all of them give "video signal: not present",
along with a staticy picture. I had noticed that a few people on the
list had success with the TCL 2002N-6A tuner. I tried it, and voila!
It worked. Well for a few seconds atleast. It doesnt matter whether I
am reading with MythTV or doing a cat /dev/cxm0, it will still reboot
after a few seconds.

Here is my cxm driver output:
