[mythtv-users] OT- CDROM woes after kernel update

So here are something you can do:

* Upgrade your bios to the latest.  There was some low level jmicron code
that started appearing in newer bios version in January.
* Upgrade you distribution (to get the latest kernel)
* Roll you own kernel if you know what your doing and are brave. (I am
neither.)


My dma access kept going away so I created this hourly cron job to turn it
back on.
#!/bin/sh
# for the dvd drive I use the keep flag
sudo hdparm -d1 -k1 /dev/hdb
# for the ide hd I don't use the keep flag
sudo hdparm -d1 /dev/hdf

Good luck,
Jon
