After searching around for quite a while I found a bug post regarding
this issue with a newer Ubuntu 4.4.0 kernel.
https://bugs.launchpad.net/ubuntu/+bug/1710419
I tried using the patch supplied in their thread on my 4.9 kernel
however I'm getting these errors:
Feb 3 13:11:48 bananapi kernel: pvrusb2: Unknown symbol
__stack_chk_guard (err 0)
Feb 3 13:11:48 bananapi kernel: pvrusb2: Unknown symbol
__stack_chk_fail (err 0)
Using insmod directly shows:
insmod: ERROR: could not insert module pvrusb2.ko: Unknown symbol in module
The issue definitely seems to be the line in pvrusb2-eeprom.c:
tveeprom_hauppauge_analog(NULL, &tvdata, eeprom);
Their patch replaces the NULL however in this case there must be
something different about the 4.9 kernel.
I also believe this is fixed as of the 4.14 kernel, I found this
reference as well:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/media/usb/pvrusb2/pvrusb2-eeprom.c?h=v4.14-rc1&id=446aba663b8240b24202cb8902b0d5c8f91aa3da
However I was hoping there was a fix so I can recompile the module for
my 4.9 kernel.
If anybody has any ideas please advise, thank you for your help.

Hello:
I have been attempting to use a Hauppauge WinTV HVR-1950 on a new
ARM-based system that has the 4.9.75 kernel (CentOS 7 for ARM). The
first time I plugged it in, I forgot to add the firmware files to
/lib. Interestingly, the kernel was fine at that point but obviously
could not initialize the device. After adding the two firmware files,
v4l-pvrusb2-73xxx-01.fw and v4l-cx25840.fw, now when plugging in the
device I get a kernel oops every time. I've done quite a bit of
searching and found a couple references to a similar issue back in the
3.x kernel but haven't been able to find anything conclusive. I have
also tried a 4.9.40 kernel as well, and receive the same result. This
device has worked flawlessly for years on an older CentOS 6 x86 box so
I know the device itself is good.
Any suggestions on what I can try, to get this working? I am
comfortable compiling the driver myself if that may help. Not sure
what do to here. I'm including the syslog below of what I'm getting
when this happens, if that helps at all.
Thank you very much in advance!
