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 :]
You mean an eastern egg? :-) The receiver did not do anything so I
plugged in the other onbe, a T230. That did not work either so I checked
dmesg. It never crashed before, only does that when you unpluf the
reveiver when it's live. This is the dmesg:
