kernel panic

[rajkumarmadhani]

Hi,

I am getting kernel panic when transferring file from PC to Device using kermit.

Below is my /mnt/jffs2 partition size:
/dev/mtdblock5 112.0M 34.2M 77.8M 31% /mnt/jffs2

still i have 77.8 MB size left in jffs2.But i am getting kernel panic.
What is reason for it, can any body tell me ....

log is below:

[rajkumarmadhani]

is there any way to check whether it is due to HW or SW problem.

from log:

Unable to handle kernel paging request at virtual address 84aa5390

Unable to handle kernel paging request at virtual address 9cb018b4

Unable to handle kernel paging request at virtual address 9caee264

Unable to handle kernel paging request at virtual address 9caee028

Kernel panic - not syncing: Fatal exception in interrupt

like this it is repeating...

Did you upgraded the ram recently or any hardware upgradation

[rajkumarmadhani]

No, i didn't upgrade RAM
