Kernel crashes after the 6.12.7 update? (solution found)
Kernel crashes after the 6.12.7 update? (solution found)
Updated my system today and it started randomly crashing, usually with these messages in journal:
#PF: error_code(0x0011) - permissions violation #PF: supervisor instruction fetch in kernel mode BUG: unable to handle page fault for address: ffffffffc0abd540 kernel tried to execute NX-protected page - exploit attempt? (uid: 1000)
Not sure if the kernel update's causing it. My mouse lags every once in a while too. Anyone else having problems?
Update:
Pinpointed the crash reason, it happens when memory usage exceeds some value. 20 ish gigs maybe? Ran memtest, got 1 pass but I'll leave it running. (Edit: left it for a couple hours, it kept passing) Also tried updating another arch system and filling its memory with stress, but that one didn't crash.
On mine I had a bunch of other packages update as well (mostly qemu stuff iirc, but qemu isn't running usually) and I also uninstalled some unnecessary dependencies listed via pacman -Qtd
. I kinda want to restore a btrfs snapshot and be done with it, but that spooks me so I sense unpleasant debugging in my future.
Update 2:
Did more testing, when used RAM+filesystem cache exceeds total ram available it pagefaults instead of emptying the filesystem cache. -_- how tf do I fix this??
Update 3:
Solution is to uninstall binder_linux-dkms. For some reason with the new kernel it causes a pagefault when purging filesystem cache which delays the purge and if that happens while system is under memory pressure programs hang. Didn't even know I had this installed
Sure don't hope so, my server runs testing 200 km away đź’€
Server's running arch on latest version?
Sounds wild, but there are surprisingly many people who use Arch on a server.
Always, yes. All of my devices. I'm not even running bleeding edge anymore, that's a blade made of blood at this point. Yet, only NVidia ever fails me (excluding AUR packages).
