Re: si2157 not working at all?

[JPT]

Well,

I was able to make a fresh ubuntu install and build 6.6-rc7

find the logfile here:
https://pastebin.com/9zsRuYFv

comments inside, at the end.
the last lines are:

si2168 8-0067: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
si2168 8-0067: firmware version: B 4.0.25
si2157 9-0063: device is buggy, skipping firmware download
si2157 9-0063: firmware version: \xff.\xff.255

so even in the newest kernel, the chip is marked as buggy.

could someone please have a look what is the problem with si2157?

here seems to be a patch for kernel 4.19

thank you very much
