Hello everyone, since a recent update on a Debian sid system, most X applications fail to start and get killed by the kernel due to a null pointer exception. The frame of the application window blinks shortly, then the application gets killed, eg:
Aug 07 21:25:14 glaurung kernel: BUG: kernel NULL pointer dereference, address: 0000000000000000 Aug 07 21:25:14 glaurung kernel: #PF: supervisor read access in kernel mode Aug 07 21:25:14 glaurung kernel: #PF: error_code(0x0000) - not-present page Aug 07 21:25:14 glaurung kernel: PGD 0 P4D 0 Aug 07 21:25:14 glaurung kernel: Oops: 0000 [#4] PREEMPT SMP PTI Aug 07 21:25:14 glaurung kernel: CPU: 2 PID: 2063 Comm: openttd Tainted: G D OE 6.9.10-amd64 #1 Debian 6.9.10-1 Aug 07 21:25:14 glaurung kernel: RIP: 0010:nvkm_gr_units+0x9/0x30 [nouveau] I downgraded the kernel and the libdrm-nouveau2 package to versions I know were functional two weeks ago, but that didn’t change the error.
