Don't know if this is related, but I am having occasional crashes
related to the CX25840, but maybe somehow also related to a cx88 /
xc2028 card also installed, a Kworld 120 PCI  card. Maybe there is a
generic issue issue with one of the drivers. Sorry for the long post,
but maybe this will shine some light on things. I can't really make
heads or tails of these messages, and there are no timestamps, but
they are suspiciously interleaved, and I have had both tuners crash
(pvrusb2 and Kworld 120), but not sure they are related.

My pvrusb2 is working fine most of the time, although I'm still hoping
for the crop changes to be included in the CX25840 driver.
