Hello,
Thanks for your reply. Actually i experienced page faults mostly
when browsing web mostly from linux opera. So i installed firefox from
ports. It didnt cause any panic until yeserday, when it caused the
crash. And after that system panic occured while booting. Well i don't
know if a particular application is causing system panic but most
panics occured when i was using net.
Can you tell me if there are any other options for kernel
configuration file which can make the debugging mor verbose? I only
used -g option in my kernel config.
I'm attaching another crash dump which occurred last night when i was
browsing net.
Greetings,
Abhijit
