If I keyed <spacebar> immediately after the Bios started booting from the kern.flp, the system crashes with a repetitively scrolling register dump. When I retried the problem, I decided to wait a couple seconds after the kern.flp was into its boot process (after the kern.flp displayed the messages "/boot.config: -P" and "Keyboard: yes"). When <spacebar> was keyed at this point, the following happened: >How-To-Repeat: 1) boot from kern.flp, hit <spacebar> as soon as the boot starts. 2) boot from kern.flp, hit <spacebar> immediately as "Keyboard: yes" is displayed, then give "-c" argument to boot prompt. >Fix: unknown >Release-Note: >Audit-Trail: >Unformatted: >> FreeBSD/i386 BOOT Default: 0:fd(0,a)/boot/loader boot: -c - int=0000000d err=00000000 efl=00030056 eip=000089f6 eax=000000b8 ebx=00002820 ecx=00000000 edx=000008ee esi=000096a1 edi=00001f98 ebp=00000ed0 esp=00001800 cs=0067 ds=0000 es=0000 fs=0000 gs=0000 ss=0000 cs:eip=0f 01 1e 76 96 0f 01 16-70 96 0f 20 c0 66 83 c8 ss:esp=0a 69 6e 74 3d 30 30 30-30 30 30 30 64 20 20 65 System halted ...the system is as described in kern/17870, save that this time I had set BIOS "PnP aware os" from yes to no, and had interrupted kern.flp booting interactively as described above. I'll try a few more things in the system's BIOS and hardware inventory; I have a very similar system running 3.4-release, so it's probably either something very subtly different between the machine configurations or something truly 4.0-RELEASE specific.
