I attempted to update my development system to today's head. After installing the kernel, etcupdate -p, reboot, installworld, etcupdate, check-old, delete-old, reboot,, the system panicked when the system tried starting the network. System is a T16-Gen1 with the Alder Lake wifi. When starting the network, it panics with: Fatal trap 12: page fault while in kernel mode cpuid = 5; apic id = 12 fault virtual address = 0xc fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff8359afd3 stack pointer = 0x28:0xfffffe00f1341c80 frame pointer = 0x28:0xfffffe00f1341d00 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 (linuxkpi_short_wq_1) rdi: fffffe016695c4f8 rsi: fffffe00f1341c48 rdx: ffffffff8118971b rcx: 0000000000000000 r8: 0000000000000001 r9: ffffffffffffffff rax: 0000000000000000 rbx: fffffe0167886e80 rbp: fffffe00f1341d00 r10: 0000000000010000 r11: 0000000000000001 r12: fffffe0167887478 r13: 0000000000000000 r14: fffffe016695c4c8 r15: fffff80003bec540 I can supply the full core.txt file.

I didn't see one with a quick look. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
