Description:    Ubuntu 10.10
Release:        10.10

The latest Lucid 2.6.32 and latest Maverick 2.6.36-rc7 kernels perform
at top performance when I hibernate. I can hibernate in 15 seconds flat.
The current Maverick kernel 2.6.35-22-generic hibernates at the near 2
minute mark. Resuming across all kernels is the same at 15 seconds.

this is my current cmdline

BOOT_IMAGE=/boot/vmlinuz-2.6.35-22-generic root=UUID=3fc3b475-04dd-4ed4
-9c3a-842580b40bf6 ro verbose no_console_suspend nomodeset
rootflags=data=writeback

I have no idea how to put the verbosity up and checking hibernate.log I
am not sure where the problem is. This is all I have in that file right
now
