JT,
Is anything getting logged? Presumably syslogd and klogd are doing
something.
Bob...
Yeah,
That would be something to check.. I'm such a newb...
checking on klogd, did the following -
from
/proc
[root@mythtv proc]# cat kmsg
<7>cx88[0]: irq pci [0x8000] ipb_dma_err*
and checking
/var/log
[root@mythtv log]# cat messages
Dec 29 18:28:50 mythtv kernel: : irq pci [0x8000] ipb_dma_err*
Of course these messages were spammed like crazy.
I am going to google these errors and search archives. If you find anything of interest let me know, as I will reply to this if I find anything.
On a side note, thanks. I have already learned a lot, I have never checked logs before... so I had to find them first!
JT
I haven't been able to find anything. Searched the following -
"ipb_dma_err* site: http://mythtv.org/pipermail/mythtv-users/ "
Since it's a mythtv system I am trying to build.
"irq pci [0x8000] ipb_dma_err* site: https://www.redhat.com/archives/fedora-list/"
On Google Linux Search
"irq pci [0x8000] ipb_dma_err" and various iterations. However all I get are kernel mailing list patch notices, or nothing.
Seems it's a PCI DMA error?
I am starting to lean towards a problem with one of the cards I have installed, just cause I can't think of anything else. Currently I have the following -
[root@mythtv proc]# cat pci

did a cat pci | grep 0x8000, but got nothing.
I don't know how to get the output of the KinfoCenter, otherwise I would paste that as well. Checking the interrupts I get -
[root@mythtv proc]# cat interrupts

also,
root@mythtv proc]# cat dma

not sure what to do past this. Thanks.
