Thank you very much for your reply.  Sure, the std kernel 2.6.6 works fine with raid1.  Or otherwise the root partition (RAID1) could not be mounted. (The problem was, apart from the root partition, no other RAID1 partition was mounted automatically.)

During the boot process, I noticed this error:

	ide_detect module not found

(The RAID comprises 2 ATA drives) I did some google searches but cannot find any help.  So I compiled a 2.6.6 kernel with IDE support built-in.  Bingo, that fixed the problem.

Trouble is, I cannot upgrade the kernel with a simple apt-get.  It will be great if the std kernel can have this problem fixed.
