And according to old usb sniffs from pctv 292e [Si2168B] default
manual ts clock is set to 7.2MHz, which means 57.6Mbit/s datarate,
it should be quite optimal for DVB-T2 max. In theory it could be a
little higher only when 10MHz channel bandwidth and most less
error correction FEC in use. And currently driver is using some
config that uses dynamic ts clock which clocks only when there is
data to feed. For some reason, usb-ts-bridge does not understand
that and manual configuration is needed (ts valid or ts-sync
connection?). If possible use 7.2MHz, if not: set to 10MHz.
That's perfectly alright with me. I'm now testing that 7.2Mhz
value. Hold on.
The driver crashes with the 7.2Mhz value! That was totally not what
I ever expected.
Recompiled the whole kernel: crashes again. Then tried on debian
kernel 4.19: same thing.
Food for thought?
It should sure never crash the kernel. Changing a ts bitrate no, no,
no, you trapped a hidden bug. Found where it is :]
I did build complete new kernel from scratch: no more crash, but no data
when set to 7.2Mhz. So definitely not possible. The crashes must have
come from me doing something else wrong.
