Re: TSTILE lockups on disk dump/backups

As I recall, the bootstrap is smart enough to be looking in the =
filesystem for the file =E2=80=9Cnetbsd=E2=80=9D, so I can just rename =
the current =E2=80=9Cnetbsd=E2=80=9D to =E2=80=9Cnetbsd.9.4=E2=80=9D and =
name the 10.1 kernel to =E2=80=9Cnetbsd=E2=80=9D and it should boot the =
10.1.kernel - right? (I tried it and it looks fine)

Which kernel is the most useful? I see:

-rw-r--r--  1 611  611  5734681 Dec 17 20:29 netbsd-GENERIC.MP.gz
-rw-r--r--  1 611  611  5721235 Dec 17 20:29 netbsd-GENERIC.gz
-rw-r--r--  1 611  611  2263029 Dec 17 20:29 netbsd-GENERIC_601.gz
-r--r--r--  1 611  611  6139563 Dec 17 20:29 netbsd-GENERIC_MD.gz
-r--r--r--  1 611  611   243443 Dec 17 20:29 =
netbsd-GENERIC_MD.symbols.gz
-r--r--r--  1 611  611  2947168 Dec 17 20:29 netbsd-INSTALL.gz
-r--r--r--  1 611  611   137756 Dec 17 20:29 netbsd-INSTALL.symbols.gz
-r--r--r--  1 611  611  2514138 Dec 17 20:29 netbsd-INSTALL_601.gz
-r--r--r--  1 611  611   112760 Dec 17 20:29 =
netbsd-INSTALL_601.symbols.gz
-rw-r--r--  1 611  611  2728011 Dec 17 20:29 netbsd-POWERMAC_G5.MP.gz
-rw-r--r--  1 611  611  2712071 Dec 17 20:29 netbsd-POWERMAC_G5.gz

Ignore the G5, 601 and symbols. (MD?) I presume that MP is =
=E2=80=9Cmultiprocessor=E2=80=9D. My machine has one processor, so I =
should use =E2=80=9Cnetbsd-GENERIC.gz, right? (That=E2=80=99s the one I =
tried)

The test case that reveals the bug only runs once a week, but I should =
be able to twist its tail and make it unhappy more quickly if I abuse =
it.

Fortunately, although  the machine is =E2=80=9Cin production=E2=80=9D, =
it is very lightly used.

Thanks for your help,
