SLES9 / IBM 7025 F50 - Problems with SMP kernel

I've just installed SLES9 on a IBM 7025 F50 with 2 processors. In contrast to SLES8 there was no problem during the installation process. The only problem is that YaST installed default kernel (non SMP). I've installed the SMP kernel that ships with the distribution, ran mk_initrd and made the relevant changes to yaboot. However this kernel won't boot the machine, in fact the boot process aborts before the kernel is loaded into memory. Is there anybody using SLES9 on a F50 with multi processor support? rgrds, Bráulio Gergull gergull@getnet.com.br
