I had one IDE hard drive for / and one SATA hard drive for /home After adding another (yet non-formatted) SATA hard drive the system panics and complains that it cannot find kernel (if I understood it correctly :).
As it happens after the GRUB(2) menu, I suspect GRUB(2). Just executed # grub-mkconfig -o /boot/grub/grub.cfg but have not tried to reboot yet. After disconnecting a new hard drive, the system boot normally. Any ideas?
