Re: [gentoo-user] Re: kernel panic -- finding proper config diff

[Maxim Wexler <maxim.wexler@gmail.com>]

Ok, I went back and found what looks like a glaring error. The old
config had the CONFIG_PHYSICAL_START=0x1000000 under processor
options, the new one was missing a zero. A ha! sez I and "fixed" it.
Nope. I get the exact same panic.

Setting CONFIG_EXT2_FS_XATTR=y doesn't help either.

On a related note, I see that CONFIG_NR_CPUS only allows for 8 in the
30 kernel. Trying any other number leads to an error "Invalid Number"
, whereas for the 29 kernel, 64 seems to be the default.
