It's chronic problem now ...
http://www.spinics.net/lists/linux-media/msg22494.html

And how I cure it for particular card.
http://www.spinics.net/lists/linux-media/msg28334.html

Now I see, to revert commit e38030f3ff02684eb9e25e983a03ad318a10a2ea is a 
necessity.

Crud, yeah, Steven was listed in the commit being reverted. Apologies,
rushed to get it out the door, heading out on vacation for a week
starting tomorrow. (Of course, I'm bringing a laptop and a few usb
devices with me...). :)

Tested and it fixed my HVR-1270 IR. I also tested a couple minutes of
live TV and it still works.

[PATCH] Revert "V4L/DVB: cx23885: Enable Message Signaled Interrupts(MSI)"

2011-06-29 Thread Jarod Wilson
This reverts commit e38030f3ff02684eb9e25e983a03ad318a10a2ea.

MSI flat-out doesn't work right on cx2388x devices yet. There are now
multiple reports of cards that hard-lock systems when MSI is enabled,
including my own HVR-1250 when trying to use its built-in IR receiver.
Disable MSI and it works just fine. Similar for another user's HVR-1270.
Issues have also been reported with the HVR-1850 when MSI is enabled,
and the 1850 behavior sounds similar to an as-yet-undiagnosed issue I've
seen with an 1800.
