Hi, I'm encountering system crash during boot with latest snapshot. Turns out that it works fine when I disable skgpio through UKC.
Have no serial console on this system so I copied this by typing it down on my second system... Guess it has the most important parts in it: [...] npx0 at isa0 port 0xf0/16: reported by CPUID; using exception 16 uvm_fault(0xd0b94520, 0x0, 0, 1) -> e kernel: page fault trap, code=0 Stopped at skgpio_match+0x2d: repe cmpsb (%esi),%es:(%edi) skgpio_match(d2165600,d2163e00,d0d1ba1c,d07fe0f0,d0d1b73) at skgpio_match+0x2d isascan(d2165600,d2163e00,1,0,d0d1bd34) at isascan+0xe3 config_scan(d07fe200,d2165600,d0d1bd8c,d03c20eb,0) at config_scan+0x8f config_attach... pcib_callback... config_process_deferred_children... config_attach... mainbus_attach... config_attach... config_rootfound...
