Hmm, something strange going on here. With this patch applied on top of 
2.6.24-rc2-mm1, I can't see no lockup or warning from kobjects code, which 
is good. But this happens:

...
Creating device nodes with udev
resume device  not found (ignoring)

/dev/disk/by-id/scsi-SATA_HDS722516VLSA80_VN6D3ECDE5BD9D-part6 to appear:  
ok

Error writing block 1542 (Attempt to write block from filesystem resulted 
in short write).

/dev/disk/by-id/scsi-SATA_HDS722516VLSA80_VN6D3ECDE5BD9D-part6: UNEXPECTED 
INCONSISTENCY; RUN fsck MANUALLY.
        (i.e., without -a or -p options)
Error writing block 1542 (Attempt to write block from filesystem resulted in short write).                                                                                         

(and this keeps looping forever).

However the very same kernel, with the very same .config, but with just 

	gregkh-driver-kset-convert-block_subsys-to-use-kset_create
	gregkh-driver-kobject-remove-subsystem_register-functions
	gregkh-driver-kset-remove-decl_subsys-macro

reverted, boots perfectly fine.
