Re: Use netconsole to troubleshoot uBoot without a serial cable

Here's the beginning of full text of the netconsole output which I extracted from Wireshark:

hd_boot=run ide_start; for scan in 0 1; do run hd_args_$scan ext2_kern ext2_boot; run ext2_rd ubi_fallback; run fat_kern fat_boot; run fat_rd ubi_fallback; done

This next line was mangled:

hd_args_0=boot_dhd_args_0=boot_dev='ide 0:1'; deev='ide 0:1'; dev_args='root=/dev_args='root=/dev/sda1'v/sda1'

I think it should read:

hd_args_0=boot_dev='ide 0:1'; dev_args='root=/dev/sda1'

Here's the rest of the printenv output:

hd_args_1=boot_dev='ide 1:1'; dev_args='root=/dev/sdb1'

nc on my laptop barfed on the first mangled packet. The trace included ICMP packets echoed back to the source saying the destination port was invalid (since nc crashed). I filtered those out to figure what that mangled line should read...

EDIT - I should also mention that I've also changed the fs type on the usb flash drive from ext3 to ext2, and modified its /etc/fstab to reflect that. Are there any init scripts or config files that I might also need to change?
