i upgraded my kernel to 2.4.21-rc2-xfs with the dm-patches (dm-2.4.20-10) and had hard crashes on booting while mounting my ext3-boot-partition (don't use xfs for root, var, usr, opt due to earlier problems, for everything other, its the fs of my choice though :-)) .
Any suggestions about patches for the jbd code (there where some changes in it from 2.4.20 to 2.4.21.x and i confess, i'm to lazy finding it out on my own, but, when nobody else did it, beharps i'll have to, booting to ext2 doesn't make me sleep too well :-) ).
My first (hum, and only) try was just leaving all the patches concerning journal_heads to jbh.h and buffer.c (and all the few other i found it in) out. Result was, that i came further, but also to a crash.
