List,
I got kernel panic when I format USB scsi hard disk.
When I run "mkfs.ext3 -j /dev/sda1" on kernel 2.6.19.2
but it is no problem on kernel 2.6.10. This also
occurs sometimes when boot up. Therefore, I believe
it is not related to mkfs.ext3 operation. PC conects
to imx31 based board by means of ethernet/usb cable.
And board mounts rootfs over nfs.
My board has two usb hosts, host1 connects PC and
host2 conects to hard disk.
Any help will be appreciated!!!
See following Oops:
