How would I restart MythTV when the failure occurs? Do you mean like having a daemon watching dmesg that restarts MythTV when this happens? That's a very ugly hack-around that will have negative side effects per below... This failure doesn't necessarily affect all tuners at the same time so I would potentially be restarting MythTV while other tuners are recording, interrupting good recordings to fix one tuner which is having a problem. I am sure you would agree that this is not really a suitable work-around, yes? > PS: Please don't drop linux-media list from Cc I don't think I did. All of my messages have been copied to the list, albeit I post them through gmane rather than posting to the list directly since I read via gmane and am not a direct subscriber to the list. Most lists will disallow postings by non-subscribers. I know vger.kernel.org does allow posting by non-subscribers on at least some of their lists but I am not aware of it being a site-wide policy or not so to be on the safe side I just let gmane post it to the list. Perhaps you got the copy I CC'd to you directly before you got the copy that went to the list via gmane.
