Hi,

This time I used Celeron to re-produce unmount problem by
using 20010206 snapshot.  This was not a Cyrix specific
problem.  So, I'm reporting this.  However, I couldn't
re-produce MBR problem although I chose the same options for
both installation on Cyrix and Celeron.

First, the unmount problem was happened when I type ^C while
the installer is newfs-ing we0e partition with above
options.  Installer said it couldn't continue and tried to
stop, then crashes.  The panic message and stack trace are:

  panic: ffs_unmount: flush left dirty bufs 0xcb0313b0
  Stopped in pid 2225 (umount) at 0xc024ba78:
  db> tr
  (null)(0,c0871400,c0873800,cb11aecc,c0232f65) at 0xc024ba78
  (null)(c030d2a0,cb031360,c0871600,0,40) at 0xc0192730
  (null)(c0871600,0,cb008394,0,cb010a84) at 0xc0232f65
  (null)(c0871600,0,cb008394,cb11af80,cb008394) at 0xc01a9f85

  (null)(1f,1f,bfbfd7bc,bfbfd79c,bfbfdc1c) at c0254c98

Or, if I installed everything smoothly, at the end of
installation, the installer says "Thank you for using
NetBSD!", then crashed like below.

  panic: ffs_unmount: flush left dirty bufs 0xcb031710
  Stopped in pid 4516 (umount) at 0xc024ba78:
  db> 

Second, I couldn't re-produce MBR problem this time.
Options what I chose are like following.  I chose the same
options for both cases, but I couldn't re-produce the
problem this time.

Is it possible that the termination of the middle of
installation avoid writing of MBR?  For example, first
installer updated only partition tables, then I quitted it.
Second installer found NetBSD partition and skip MBR
installation.
