Hi
ab17c4f02156c4f75d7fa43a5aa2a7f942d47201 is the first bad commit
(reiserfs: fixup xattr_root caching)
Kernel panics when init tries to remount rootfs (reiserfs) with
read-write access.
Read-only access works fine.
No more messages on the screen before panic.
Is it endianess related?

No, not at all. There was a problem with the xattr code if the kernel
was built with xattrs disabled. It assumed that
REISERFS_SB(s)->xattr_root would be available, which isn't the case when
xattrs aren't enabled. Part of it has been cleaned up in -git1, and I've
sent Al some additional patches to fix the rest of it up.
There's a thread called "reiserfs xattr fixups" that contains 4 patches.
The patch marked with * is the one I believe will fix your problem.
- - reiserfs: cleanup ifdefs
- - reiserfs: deal with NULL xattr root w/ xattrs disabled *
- - reiserfs: fixup perms when xattrs are disabled
- - reiserfs: allow exposing privroot w/ xattrs enabled
