about my own experiences with an odd page fault issue in mythfrontend
0.19. Now I can report that the exact same thing [1] happens when
exiting a certain HDTV cable recording done in December 2005. It's
possible this has something to do with transcoding, as I did so with
the recording earlier tonight, but given the experience with the tuner
card I don't think so.
[1] Well, I *think* it's the same thing. Same non-instability of the
system, too. Backtrace from dmesg follows:
Bad page state at free_hot_cold_page (in process 'mythfrontend', page c1280d60)
flags:0x80000400 mapping:00000000 mapcount:0 count:0 (Tainted: PF B)
