Hi all...
Ok, so I'm having some rather MAJOR issues with system stability... I have
a rather complicated setup... and am having DMA issues... big time.. and
think perhaps I have some IRQ sharing issues. First, let's talk about my
software and hardware...
Running Gentoo 2.6.19-r5 ... with ivtv-0.10rc1 ... (have been using
0.9.1for a long time... with the same problems)
Gigabyte GA-7VT600-L (VIA Chipset)
Athlon XP 3200+
1GB RAM
PDC20268 TX2 ATA-100 controller
2x PVR-350
1x PVR-500
4x WDC WD2500JB-00REA0 250GB disks...
1x ATAPI DVD-RW
The disks are connected one each to the primary channels of the adapters...
the DVD drive is connected as a slave on one channel.. like this:
hda - 250GB
hdc - 250GB
hdd - DVD
hde - 250GB
hdg - 250GB
They are configured in various software RAID configurations... blah blah...
when my system crashes, I typically see that the main RAID-5 array on which
my recordings reside.... goes through a resync... which leads me to some of
the conclusions below...
Ok... so... I'm getting these type of errors...

Now... I'm not sure what the ivtv0 DMA errors are... but I'm thinking the
latter errors... related to /dev/hde and /dev/hdg ... are perhaps problems
with what I see from /proc/interrupts

Specifically... what I see about /dev/hde and /dev/hdg sharing IRQ 16 with
ivtv3 .. which is the #2 channel on my PVR-500 ... I'm not sure how much
moving cards around in this system I can do to free up IRQs... gonna trying
disabling my USB adapters... since I don't need them... we'll see... here's
the output of my ivtv driver load... in case it'd help anyone.

If anyone can offer me a clue... that'd be great... this thing is so damned
unstable these days... it's drivin' me crazy.
