How do I make an alien technology feel alien? Please Append A Correct Root= Boot Option Here Are The Available Partitions I hope this article sheds some light on your woes. It seems that when you compile a new kernel, the reiser file system will not access the hard drive without some manipulation with the reiserfs tools. And also the one mentioned in the error msg.
It is perfectly ok to point grub to a kernel on (hd0,0) and tell the kernel that you mean sdb for root.

The init script located under /etc/init.d/kdump performs some search & replace changes on the collected string so it is good enough for the Kdump kernel. While some of the items may not be applicable for the Kdump kernel, you will get a pretty good indication if you're trying to do something that conflicts with reserved segments. One of the most frequent cases: you selected support for your harddisk controller protocol (IDE, SATA, SCSI, ...) but forgot to select the HDD controller driver itself (like Intel PIIX).
