During the last week I have seen two lockups on my alpha,
Digital AlphaPC 164LX 599 MHz, s/n
8192 byte page size, 1 processor.
total memory = 512 MB
(2120 KB reserved for PROM, 509 MB used by NetBSD)
avail memory = 492 MB
cpu0 at mainbus0: ID 0 (primary), 21164A-2
cpu0: Architecture extensions: 1<BWX>
%uname -s -m -r
NetBSD 3.99.3 alpha
I think it might be disk related. I was doing 'make configure' in
www/firefox when the last hang occured. Everything just stopped. X is
still there and the image is not damaged in any way (graphics errors, or
so). It is not possible to break from X into the debugger when it
happens (well, that is the general feeling anyway, after trying all the
key combos in the book). Perhaps I can hook up a serial console some
The machine still responds to ping after being frozen.
Pressing caps lock / num lock will not light the LEDs.
I believe I have enough cooling on both the computer and the disk. The
disk is a,

I used to have softdeps on /usr and /home, but am now running with it
turned off to see if that makes some kind of difference (having read
about others who can lock up their NetBSD boxes with softdep..).
