Dear Gurus,
I have a Digital Personal workstation(433au) with DU4.0D and the
root and /usr are AdvFS. Suddenly yesterday I found that it does not boot
up and the following messages come up:
kernel stack invalid
PC = 0
boot failure
halting CPU
This message come up when its supposed to boot the kernel. I tried the
following but gave the same messages :
>> boot genvmunix
and
>> boot vmunix
What could be the problem? Is it that the kernel is corrupted? Thinking so
I moved the disk to another system(same but with DU4.0B) and tried to mount
it. The following were done:
___________________________________________________________________________
# /sbin/advfs/advscan rz22
Scanning devices /dev/rrz22
Found domains:
*unknown*
Domain Id 374a7681.00068495
Created Tue May 25 15:08:01 1999
Domain volumes 1
/etc/fdmns links 0
Actual partitions found:
rz22a*
rz22c*
____________________________________________________________________________
____________________________________________________________________________
# /sbin/advfs/advscan -r rz22
____________________________________________________________________________
This created the domain without any problem.
____________________________________________________________________________
# mkfset domain_rz22a root_parrot
ADVFS : Domain domain_rz22a not activated - inconsistency detected
mkfset: can't create file set 'root_parrot' in domain 'domain_rz22a'
mkfset: error = E_DOMAIN_NOT_ACTIVATED (-1067)
____________________________________________________________________________
I tried checking the file domain:
____________________________________________________________________________
# advscan -f domain_rz22a rz22
Scanning devices /dev/rrz22
Attempting to fix link/dev_count for domain
domain_rz22a
Nothing to fix

My basic idea was to copy the generic kernel to the damaged system
disk after mounting the disk in the second machine.
Any suggestions please.
Thanks in advance,
