Unfortunately I got a kernel panic during install. It's reproducible and happens directly upon loading device bge0. Disabling ACPI doesn't help. Verbose logging gives some additional info, see below. Here's the trace with ACPI: bge0: Ethernet address: 00:0b:db:e4:47:a0 bge0: MII without any PHY! Fatal trap 12: page fault while in kernel mode cpuid = 0 ; apic id = 00 fault virtual address = 0x4 fault code = supervisor read, page not present instruction pointer = 0x8:0xc04eba26 stack pointer = 0x10:0xc1021a00 frame pointer = 0x10:0xc1021014 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL0, pres1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 0 (swapper) trap number = 12 panic : page fault cpuid = 0 uptime : 1s With ACPI disabled, the stack and frame pointers change: stack pointer = 0x10:0xc1021ab4 frame pointer = 0x10:0xc1021ac8 When booting with verbose logging on, there a little bit of extra info that is still on the screen when the kernel panics: "pcib1 : device bge0 requested decoded memory range 0xe200000-0xe020ffff". This behavior is reproducible. The addresses I mentioned do not change. I have this feeling the problem is with bge0 :) I hope this helps. For now, I'm happy with 4.9 despite the kernel panics with AC adapter. 5.1 did better with that but had trouble with my PCMCIA wireless (BElkin) adapter. Ah well - life just doesn't want to be perfect, does it? Maurice van Steensel
