Hi,

    Subject: Re: kernel won't start on i386
      Date : Fri, 11 May 2001 19:49:17 +0200 (CEST)

$ This is similar to the problems I wrote I was having with -current
$ on an IBM 600 laptop, except that:
$ 
$ |   booting wd0a:netbsd - starting in 0
$ |   2422950+35300+168700 [65+129968+94525]=0x2b9498
$ |   [stops here after CRLF--no further output]
$ 
$ Instead of stops_here, I get resets/reboots immediately.
$ 
$ | The currently working kernel is 1.5S from March 15, and I also successfully
$ | booted the 1.5T GENERIC kernel from the April 7 snapshot.
$ 
$ I have an April 19 kernel working.  Nothing after about 5 May has worked for 
$ me on the laptop.

Would you please try below 1 or 2?
      1. next patch
      2. revert sys/arch/i386/i386/machdep.c rev = 1.431
