[mythtv-users] FFWD and MUSIC crash my system

Hi!

I was wondering if anyone had an idea what these error messages in 
my /var/log/messages mean and if they may have any relationship with the 
system hangs I experience when I do a fastforward of a recording, after a 
while when I watch a recording (even with no ffwd) and when I listen to 
music.  I am using the hardware encoding and decoding from my PVR-350 as well 
as the TVOut functionality.

I suspect it may be related to the ivtv driver, but I am not sure and I donīt 
know how to troubleshoot any further at this point.

This is my setup:
EPIA M10000
PVR-350
Fedora Core 2 (2.6.10-1.770_FC2)
ivtv 0.2.0 (rc3i)
lirc 0.7.1[3180]
MythTV 0.18.20050409-1
MySQL Ver 11.18 Distrib 3.23.58, for redhat-linux-gnu (i386)

/VAR/LOG/MESSAGES  (and at the end of this e-mail is the full IVTV section in 
meesages):
