2.4.20pre5 CONFIG_BLK_STATS breaks LVM tools
If CONFIG_BLK_STATS is enabled in 2.4.20pre5 this breaks at least the LVM tools. The symptom on a system running initrd to do vgscan/vgchange to be able to boot is that after
RAMDISK: Compressed image found at block 0
Freeing initrd memory: 734k freed
VFS: Mounted root (ext2 filesystem).
the system hangs with the CPU under load. It is difficult for me to investigate this further as both systems I do have available run a LVM/reiserfs only setup and thus I can't have a look at the layout of /proc/partitions in the CONFIG_BLK_STATS enabled page.
It would, however, be worth a word of warning in Configure.help that this option can break userspace tools that may be important for system boot and other system functions.

Andreas,
this is a known issue and I am working on a patch to send to Marcelo.
Try removing the add_gendisk() call (~line 460) in drivers/md/lvm.c and retry as a workaround for now,
