(The lirc_zilog is now in the kernel, yay) There's a bit more to it than just the one line change. Here's the patch we're carrying in the Fedora kernels to enable it: http://wilsonet.com/jarod/lirc_misc/hdpvr-ir/hdpvr-ir-enable.patch Janne, I've heard many success stories w/the hdpvr IR lately, and almost no reports of lockups, so I'm thinking a firmware update may have helped out here, and thus, maybe its time we just go ahead and push this patch along upstream? We still require someone to load lirc_zilog manually, so it seems like a fairly low-risk thing to do. -- Jarod Wilson jarod@xxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
