kernel panic
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:
