Re: Error : panic (cpu 0): Processor Machine Check
at boottime this is analyzed to produce a textfile in the same dir with hints of what produced the crash.
maybe this helps

Re: Error : panic (cpu 0): Processor Machine Check
Thanks Peiter for the reply. Yes it did generate a crash dump file.
I have tried to analyse the extract w.r.t. the time when the System Panic. i.e. on Feb 14 at 01:38.
Please find the relevant crash dump file and suggest if there is any hardware issue.

Re: Error : panic (cpu 0): Processor Machine Check
A more interesting output would be the console log at the time of the crash - that would have the exception frame and associated output. An Alpha H/W person could then suggest what might be faulty. In fact the console output may even suggest the nature of the fault in human readable text.
I see the system had been up for 6 months - If it doesnt suffer another Machine Check in the near future, I guess you could always 'ignore' it.... Or was the previous reboot last year due to a similar fault ?

Re: Error : panic (cpu 0): Processor Machine Check
I could manage to take a note of few of the console logs at the time of crash. Like the system was showing the messages like,

ata1: CYPRESS 82C693
scsi2 at ata1 slot 0 rad 0
usb0 at pci0 slot 305 (slot 5, function 3)
aha_chim0 at pci0 slot 6
Adaptec AIC-7895 Adapter : H/W Rev 4, Driver Rev 2.274 CHIM V364A5
scsi2 at aha_chim0 slot 0 rad 0
aha_chim2 at pci0 slot 106
Adaptec AIC-7895 Adapter : H/W Rev 4, Driver Rev 2.274 CHIM V364A5
scsi4 at aha_chim2 slot 0 rad 0
ee2 at pci0 slot 7

ee2: Driver Rev =

isp1 QLogic
isp1 Firmware
isp1 Fast RAM
halted CPU0

Any help from this?

Re: Error : panic (cpu 0): Processor Machine Check
Yes last year similar boot happened but for some other reason. Like Battery charge was the issue.

Re: Error : panic (cpu 0): Processor Machine Check
EV5 - download DECevent and use it for translation of the binary.errlog.
http://h18023.www1.hp.com/support/svctools/decevent/index.html
EV6 or higher download SEA and use it for translation. SEA is a part of the WEBES toolkit

Re: Error : panic (cpu 0): Processor Machine Check
with a little browsing through your data I finally extracted
a little info that should -in the end- help us to help you :)
From the snippet of the crash-data that you provided I read this:
--------------
Hostname : ---snip---
:
COMPAQ AlphaServer DS20E 666 MHz avail: 2
:
2 kn600_machcheck(0x100000000, 0x0, 0x4, 0xfffffc0000006120, 0xfffffc0000006080)
3 default_mach_error(0x4, 0xfffffc0000006120, 0xfffffc0000006080, 0x0, 0xfffffc000067c060)
:
--------------
That answers the question of what tool to use next
The above shown snippet from the crash-data shows the beginning of the stacktrace.
It would not be really helpfull. Here we have to look at the Machinecheck-Frame
which is in detail (normally/mostly) to find in the binary.errlog .
You need to use WEBES (here "wsea" formerly known as "ca") to analyse /var/adm/binary.errlog

--Uwe.
