I have a fix in my mind - but to verify the fix, either install a test kernel I provide or compile a patched kernel by yourself will be required.
So I guess nothing more we can do here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1937031 Title: GPF in rtl2832 Status in linux package in Ubuntu: Incomplete 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.
