Mike, the PnP probe you added panics my HP800CT during boot. With -v it prints (typed from barely legible notes:) PnPbios: Found PnPBiosdata 0xc00ff000 PnPbios: Entry e8000:33e1 rev 1.0 PnPbios: eventflag at e801b OEM ID 1826744e and then panics with a pagefault at EIP: %058:0x343e, fault address 0x100e. Adding some debugging showed me that this happens on the very first call to bios16_call(). The funny thing is, this happens after a cold boot (hard reset), and goes on until I have booted my /kernel.good (from before your change) just once. After that, and until next hard reset a -current kernel boots just fine. Smells like som unitialized data or something to me... -- Poul-Henning Kamp FreeBSD coreteam member [EMAIL PROTECTED] "Real hackers run -current on their laptop."
