Some news after new tests. I've reinstalled all Mesa + xorg + nvidia related package in force mode on my TW (now at 202102019 version) After the reboot I got a new type of trace with 5.10.16 kernel [f���v21 17:28] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20200925/nsarguments-61) [ +0.828215] BUG: unable to handle page fault for address: ffff8abec59ea004 [ +0.000003] #PF: supervisor write access in kernel mode [ +0.000001] #PF: error_code(0x0003) - permissions violation [ +0.000000] PGD a95001067 P4D a95001067 PUD 100ef2063 PMD a941fc063 PTE 80000001059ea161 [ +0.000003] Oops: 0003 [#1] SMP PTI [ +0.000002] CPU: 3 PID: 1885 Comm: Xorg.bin Tainted: P OE 5.10.16-1-default #1 openSUSE Tumbleweed [ +0.000001] Hardware name: Dell Inc.
