[MASOCH-L] Ajuda com kernel panic

[Eduardo Schoedler]

Bom, meu CFLAGS está assim:

# cat /etc/make.conf
CHOST="x86_64-pc-linux-gnu"

CFLAGS="-march=nocona -mtune=nocona -mfpmath=both -O2 -pipe -mmmx -msse
-msse2 -mssse3"
CFLAGS="${CFLAGS} -fomit-frame-pointer -fno-ident"  # a little "cleanup"
CXXFLAGS="${CFLAGS}"

Posso tentar tirar o "fomit-frame-pointer", andei lendo que ele pode mais
atrapalhar do que ajudar...
