Dear Sudheer,
I am not that much expert in linux
internals. Hope some one will answer your queries.
But I found some interesting thing in
linux device driver – Alexandro rubini book – chapter 4, heading “System Hangs”
Hyperlink:

Please check whether it will give any idea/hint
to solve this problem.
Thanks
Manjunath

Subject: Re: regarding kernel
error before it hangs
Hi Manjunath,
While working with the driver, sometimes the kernel hangs. The kernel
doesn't report any log messages ( error messages) on the console nor in
the /var/log/messages . So I am not able to find the reason for
kernel hang.
I want to know wether this problem might be with s/w or h/w. If the
problem is with s/w , i assume that kernel will definetly report some error
message.
Am i right ?
Pl help me and correct me if i am wrong.
Thanks
Sudheer

Can you elaborate more on this? Whether the kernel does not
log anything to system logs or not?
Hello All,
Normally while working with drivers, kernel gives error messages like
panic/oops if any error occurs and even before "kernel hangs".
I want to know wether will there be any situation that kernel hangs but doesn't
print any kind of error mesages if any problem in the driver.
I want to know this bcoz i am facing this problem and not able to decide wether
it is driver problem or hardware problem. The kerrnel hangs but doesn't print
any error mesages.
Pl help me.
Thanks
Sudheer
