i am having this exact problem, the init-script run fsck, and not the default kernel does not boot.
the important lines say: mounting root filesystem on ide0(3,8) mount error 22 mounting ext3 defaults ext3 no journal on filesystem on ide0(3,8) using a self compiled 2.6 kernel (with ext3 built in) i can boot this machine. can anyone guide me fixing the default mandrake kernel boot? (fsck run ok gives no errors while botting the rescue disk) - diego
