[P]roblem: --------------------------------------------------------------
Our Alpha Server 2100 4/200 is crashing on boot up.
I was attempting to rebuild the kernel. Here's the steps I took up until
the crashing started.
# cp /vmunix /usr/vmunix.save
# cp /genvmunix /vmunix
# /usr/sbin/shutdown -r +5 "Shutting down to build new kernel"
upon reboot the system crashes with the following. It starts to boot
and gets to a certain point and then
trap: invalid memory write access from kernel mode
faulting address: ...
pc of failure instruction:
ra contents at time of fault:
sp contents at time of fault:
panic (cpu 0): kernel memory fault
syncing disks
DUMP:
What do I need to do get get the system up quickly. Or is this root disk
gone south.
[A]nswer: ---------------------------------------------------------------
Thanks to those quick responses from.

All suggested I try booting up into single user.
>>> boot -fl i
I had tried this before but it still crashed the system.
I tried again and it worked. I had tried booting the generic kernel
but it always crashed the system. We've never had this problem before
with booting the generic kernel.
>>> boot -file genvmunix also did not work.
Once into single user I did the following:
# bcheckrc
# doconfig
new kernel built fine and booted correctly. I am still concerned after
seeing on boot up something about bad sector on disk.... I did not
however see it again after powering off/on the system and rebooting.
thanks again.
