You can send the crash-data file to the canasta server
for initial analysis
"To request a diagnosis, send mail whose content is one of the
above files and whose subject looks like:
DIAGNOSE [<platform>] [CASE_ID=<case_id>] [CUSTOMER_ID=<customer_id>]"
to the mail address [email protected]
From the data in the note, you may be able to find out
the culpret from this information:
trap: invalid memory ifetch access from kernel mode
faulting virtual address: 0x0000000000002000
pc of faulting instruction: 0x0000000000002000
ra contents at time of fault: 0xfffffc000051665c
sp contents at time of fault: 0xffffffff83833640
Using the ra, map that address as an instruction
# kdbx -k vmunix.0 vmcore.0
(kdbx) 0xfffffc000051665c?20i # Get the instruction stream prior
(kdbx) 0xffffffff83833640/20X # Contents of the stack
Since this appears to be a 4.0B system you will probably want
to QAR/IPMT the problem.
