Hi,
I'm facing a problem with a hanging/non-responding capture from my
PVR 500 card.
I've tried to find some leads elsewhere - but none seems to match
my problem.
The ivtv-users list did not give any responses at all so I'm trying
here as suggested by the "asking for help" instructions.
Symptoms:
When either attempting watching live TV in MythTV or
"cat /dev/video0 > test.mpg" a hang persists for a couple of seconds
and no output is generated.
This happens at every attempt.
The hang only happens for the capture - the rest of the system is
responding as normal.
The hang for the cat /dev/video0 > test.mpg is seen when ctrl-C is
pressed - this takes a couple of seconds to terminate the command.
Problem reproduces using both ivtv 0.4.4 and 0.4.6
Interestingly the problem only occurs if I allow the CPU to map devices
out of the normal 32-bit memory address space.
A simple workaround is therefore to disable this functionality, but
this will disable around 700MB from my 4GB of RAM, which is obviously
not a preferred solution.
Any suggestions ?
Error messages (from dmesg):
ivtv0 warning: ENC: REG_DMAXFER 2 wait failed
ivtv0 warning: DEC: REG_ENCSG1LEN wait failed
ivtv0 warning: ENC: DMA still Pending while stopping capture!
System info:
ASUS A8V Deluxe motherboard with the Via K8T800 Pro chipset (yep, the
one with incompability problems with PVR500 - solved by setting PCI
latency timer to 32 and by using newest BIOS)

4GB RAM
SuSE 10 (kernel 2.6.13) - 64 bit version

irrelevant information about USB, NIC and APG stuff):
