But, twice in a row now I've made this happen:

 All I have to do is run my script, it tries to extract the kernel
tarball, and tar hangs in D state.

 How do I debug this?  (Is there some way to get the output of Ctrl-ScrLk
to go to the log instead of just the console?  My system isn't currently
hung, it's just got a process that is.  This process being hung prevents
my partitions from being unmounted on shutdown, which is annoying.)

sysrq-T followed by `dmesg -s 1000000 > foo' should capture it.

I'll give it a try...

Okay, I reproduced the hang.  Now...  It's beeping at me?

It helps to have magic sysrq selected in menuconfig.  I'll get back to this...

 Other miscelanous bugs: cut and paste only works some of the time (it
pastes blanks other times, dunno if this was -test5 or -mm2; it worked
fine in -test4).

vgacon? fbcon? X11?

X11.  At first I thought it was only between certain apps, but now I thin it's 
just plain intermittent.  Smells like a race or uninitialized variable or 
something.  (For all I know, the bug could be in kde, although I'm using 
RH9's binaries.  I've seen it cutting and pasting between kmail, konsole, and 
konqueror.  Sorry, can't reproduce this one at will...

 The key repeat problem is still there, although still highly
intermittent.

I think Andries says that some keyboards just forget to send up codes.
We'll probably need some kernel boot parameter to support these, using the
keyboard's silly native autorepeat.

I'd rather not have any autorepeat at all than have it go intermittently nuts 
on me...

 The boot hung enabling swap space once.  I don't know why.  (Init was
already running and everything...)

Probably the O_DIRECT locking bug: I had `rpmv' getting stuck on boot for a
while.  mm3 fixed that.

I'll upgrade after I get you your sysrq-t.
