[gentoo-user] emerge -e system problem.... kernel error

[Marco Calviani]

Hi list,
   i'm having big trouble in running emerge -e system after a gcc
upgrade (from gcc-3.4.4 to gcc-3.4.5. This is coming from dmesg:

------------[ cut here ]------------

        spin_lock_irq(&ip->ioc3_lock);

        spin_unlock_irq(&ip->ioc3_lock);

        return 0;
