| |
I tested 2.4.25 on Intel S875WP1 mainboard. Whren I run a normal SMP kernel, it works fine. When I give it a "nosmp" boot option (an no other special options), it fails to boot while detecting IDE devices. The IDE is Intel ICH5 (ICH5-R?) on a 875P chipset. The hdd's are detected hde and hdg normally. With "nosmp", it tells hde: interrupt timeout (or was it lost interrupt) and this repeats after some time.
So probably the IRQ routing is broken in nosmp. Is this normal somehow?
Have not tried UP kernel.
