Subject: GP fault in cx18 module from v4l-dvb drivers on linuxtv.org (Ubuntu 17.04)
Date: Tue, 29 Aug 2017 19:43:21 -0500	[thread overview]
Message-ID: <CAAxvtFYjbGzEHi0PTVG+c=HYMZ+7bORcpYXZSVfG1yZ7qndzQg@mail.gmail.com> (raw)

Having a problem with a #GP fault when loading the cx18 driver from
v4l-dvb from the linuxtv.org site.


Device:  Hauppauge HVR-1600 (lspci output at pastebin.com/e7G52kqQ)
(ATSC signals)

Environment:  Ubuntu 17.04, kernel 4.10.0-33-generic, 64-bit

Hardware:  Motherboard:  Gigabyte GA-B150M-D3H  (16GB RAM)


I've downloaded the v4l-dvb kernel drivers, built them, and installed
them.  I was unable to use the built-in drivers as I needed the
cx18-i2c driver.


>From the stack trace included with the pastebin link above it appears
the problem is in find_ref_lock() when called from c18_probe() if that
helps immediately.


Things I've tried:

    -- Remove kernel drivers/Reboot/Install v4l-dvb
drivers/build/install/modprobe

    -- Do a 'make rminstall' to remove drivers and attempt
install/modprobe again


I found it interesting that even though the #GP happens and the /dev
entries are not created, the cx18 module still loads (as found with
lsmod) but no cx18-i2c was loaded.
