I also see these timeout messages when booting a -current kernel on my
386DX/40, 16MB, IDE LPS240AT system, i.e., the current wdc.c is
completely broken for me. I hacked the old wd.c from 0.9 to compile
with -current and that works for me. Not that I'm happy with this....
What has changed?

BTW: Is there any good reason why NetBSD does *not* adopt VC's
(virtual consoles)? They are indispensable when working without X,
i.e. on a laptop. Linux even offers mouse-based cut-and-paste between
VC's ala xterm. Nice. Does syscons or pcvt work with NetBSD-current
and XFree-2.0?

Another note: Why in the world is everything compiled with -O? I
remember that -O == -O1, and that many (most) gcc optimizations are
only enabled with -Ox (x >= 2). What about -fomit-frame-pointer?
The 486 has so few registers that this does pay off. Linux compiles
*everything* (kernel, libc, user progs) with -O2 -fomit-frame-pointer.
What about gcc 2.5.8?

Currently I'm working on merging the Intel Pentium/486/386 gcc
extensions into 2.5.8, and I'll try to 'make world' when I succeed.

PS: I patched my sys.mk to use -O2 -fomit-frame-pointer by default,
    but I'm chicken and didn't use that for the kernel so far.
