Subject: How could I record the information when kernel panic.
Date: Thu, 25 Apr 2013 01:18:24 +0800	[thread overview]
Message-ID: <517813E0.8070701@gmail.com> (raw)

There is a random probability that cause the kernel panic (debian with 
kernel 3.2.41), when I execute:
"sudo umount /media/data /media/big".

Things are like this:

I use "udisks --mount /dev/sda3" to mount "data" which is a ntfs filesystem.
similarly, I use "udisks --mount /dev/wd5000bpvt/big" to mount "big" 
which is a ext4 filesystem.

After finish using these filesystems, I use "sudo umount /media/data 
/media/big" to umount the filesystems, and the hole system just suddenly 
halt (mouse is not moving).

using alt-sysrq-b to reboot the system. nothing record in the 
/var/log/messages.

So, How could I record the kernel error/info, when system was halt ?

Thanks a lot!
