Hi! I've upgraded my system to 14.3-BETA3. Now sometimes right after the system boots up I have this message: Fatal trap 12: page fault while in kernel mode cpuid = 5; apic id = 05 fault virtual address = 0xbe34af50 fault code = supervisor read data, page not present instruction pointer = 0x20:0xbddc3907 stack pointer = 0x28:0xfffffe0036169c50 frame pointer = 0x28:0x1 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (thread taskq) rdi: fffffe0036169d18 rsi: fffff80001b85c60 rdx: 0000000000000000 rcx: 00000000bddc5158 r8: 00000000bddc53d8 r9: 0000000000000004 rax: 00000000be34ae10 rbx: fffffe0036169de8 rbp: 0000000000000001 r10: 0000000000000000 r11: 0000000000000013 r12: fffff80001b91a58 r13: 0000000000000000 r14: fffffe0036169e20 r15: fffffe0036169dc0 trap number = 12 EFI RT page fault Also I have this message since 14.0 or so (these two seems to appear independently): drmn0: [mmhub] page fault (src_id:0 ring:157 vmid:0 pasid:0, for process pid 0 thread pid 0) drmn0: in page starting at address 0x0000000006003000 from client 0x12 (VMC) drmn0: MMVM_L2_PROTECTION_FAULT_STATUS:0x0000073A drmn0: Faulty UTCL2 client ID: DCEDMC (0x3) drmn0: MORE_FAULTS: 0x0 drmn0: WALKER_ERROR: 0x5 drmn0: PERMISSION_FAULTS: 0x3 drmn0: MAPPING_ERROR: 0x1 drmn0: RW: 0x0 My drm module is 6.1.92.1403000_3 (I recompiled this version after updating to 14.3). My GPU is AMD's dimgrey cavefish. The system works as usual despite the messages. Do I need to worry about it?
