Hi,

Installing Gentoo on a Net4801 but Kernal panics, below are the last
lines before panic:

The above error is pretty clear. 240=128+64+32+16 so look into what
the ext*fs option bit mean, and make sure your kernel has the options
enabled.

Thanks for quick reply.
Why does it attempt to mount as ext3 (EXT3-fs) since sda is in ext4?
I probably missunderstand the process...

Hi,

Still struggling to get my Soekris to boot.
Here is the full boot sequence: http://paste.pocoo.org/show/509089/

Can't see anything obvious, is there any way to have logs more verbose?

Thanks

This seems to be the real reason:

[ 9.807170] [<c1002fb6>] ? do_invalid_op+0x86/0xa0

Your /sbin/init uses instructions the SC1100 doesn't recognize.
You probably should rebuild world with CFLAGS="-march=i586" or even lower.
