Okay, I've banged my head against this for a few weeks now, I give up. Someone tell me what I'm doing wrong... Following the directions at http://sources.redhat.com/redboot/ipaq/ yields the following kernel bootup: RedBoot> fi load Linux RedBoot> ex -b 0x100000 -l 0x80000 -c "noinitrd root=/dev/mtdblock3 init=/linuxr c console=ttySA0,38400" Uncompressing Linux....................................... done, booting the ker nel.

I can't find any explanation anywhere of why it should be 'mtdblock3', but mtdblock[0-8] all give the same error.

Notably, the same one that was giving wierd serial issues two weeks ago...) Thanks, david
