I just tried v2.6.30-8722-gc82e6d4 on VirtualBox (x86_64) and got a crash.
Last tested/working version: v2.6.30-6553-g65795ef.

Call trace:
   generic_acl_init
   shem_acl_init
   shmem_mknod
   vfs_mknod
   sys_mknodat
   ...
   system_call_fastpath

Please see attached screenshots for full details.

Cheers,
FJP

(Thanks to Eric Paris for the very quick fix for the audit build failure.)

Fixed in vfs-2.6.git for-linus...

Pulled, built, tested, check...
Wow, we're fast today.

Looks like resource allocation got improved:
-pci_bus 0000:00: resource 0 io:  [0x00-0xffff]
-pci_bus 0000:00: resource 1 mem: [0x000000-0xffffffffffffffff]
+pci_bus 0000:00: resource 0 io:  [0x00-0xcf7]
+pci_bus 0000:00: resource 1 io:  [0xd00-0xffff]
+pci_bus 0000:00: resource 2 mem: [0x0a0000-0x0bffff]
+pci_bus 0000:00: resource 3 mem: [0x10000000-0xffdfffff]

Thanks,
FJP

P.S. Just see we're rid of 'Driver 's{dr}' needs updating - please use 
bus_type methods'. Yay!
