Title:
GPF in rtl2832
Status in linux package in Ubuntu:
Expired
Bug description:
I'm using a nooelec "nesdr smart" and GnuRadio - however every time i try to
run the gnuradio program, i get a kernel fault. the computer then seems to be
unusable. it doesn't crash, but it becomes unstable - various programs don't
work correctly, can't edit files... the only way to resolve this is to reboot.
The problem appears reliably every time. I get a an error reported,
which i can see with dmesg. I can't save the error to a file - as
saving files doesn't seem to work correctly after this error (e.g. vi
error.txt, then save will hang)
I'll add some details about the error here, and attach a screenshot.
(this is me transcribing the screenshot, so hopefully accurate!)
