Re: Linux2.6.10-rc3 for 8xx booting "load_kernel(...)" function prob lem vs configuring and initializing serial console ?

["Raphael Bossek" <raphael.bossek@gmx.de>]

Hi Alexander,

sorry, but I'm using Wolfgang's (www.denx.de) kernel 2.4.20 from CVS for
8xx. I did not move to 2.6 yet because there was no reason (and Wolfgang 
does not support it yet, does not?).
