(package changed to linux as "kernel fault" is mentioned; probably should be gnuradio) ** Package changed: ubuntu => linux (Ubuntu) -- 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: New 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!) general protection fault: 0000 [#1] SMP PTI CPU: 3: PID: 866 Comm: kworker/3:3 Tainted: P Workqueue: events rtl2832_i2c_gate_work [rtl2832] call trace: ? __switch_to_asm+0x40/0x70 ? __switch_to_asm+0x34/0x70 ? __switch_to_asm+0x40/0x70 ? __switch_to_asm+0x34/0x70 ? __switch_to_asm+0x40/0x70 ? __switch_to_asm+0x40/0x70 ? __switch_to_asm+0x34/0x70 ? __switch_to_asm+0x40/0x70 ? __switch_to_xtra+0x1ae/0x5e0 ? __switch_to_asm+0x40/0x70 ? __switch_to_asm+0x34/0x70 ? __switch_to_asm+0x40/0x70 ? __switch_to_asm+0x40/0x70 __mutex_lock_slowpath+0x13/0x20 mutex_lock+0x2e/0x40 regmap_lock_mutex+0xe/0x10 regmap_update_bits_base+0x3b/0x90 rtl2832_i2c_gate_work+0x31/0x70 [rtl2832] process_one_work+0x1eb/0x3b0 RIP: 0010:__mutex_lock.isra.0+0x78/0x4f0 uname -a Linux beasty 5.4.0-77-generic #86-Ubuntu SMP Thu Jun 17 02:35:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Memory: 65678960K/67040508K available (14339K kernel code, 2400K rwdata, 5008K rodata, 2736K init, 4964K bss, 1361548K reserved, 0K cma-reserved) CPU0: Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz (family: 0x6, model: 0x5e, stepping: 0x3) happy to supply further information if required.
