Description Bjarke Istrup Pedersen 2007-08-09 01:10:10 UTC

Most recent kernel where this bug did not occur: 2.6.21
Distribution: Gentoo
Hardware Environment: VMWare virtual machine, 1gb ram, 18gb harddrive
Software Environment: Shouldn't matter in this case
Problem Description: The system hangs for a long time when booting, just after it has printed "Decompressing Linux..." on the screen.
After a while, it wakes up and continues booting.

Steps to reproduce:
Try booting a 2.6.22 x86_64 kernel on a vmware virtual machine.

There is a patch for this, just scroll down to the third post in here:
http://groups.google.com/group/linux.kernel/browse_thread/thread/caa18c4b4fc12279/1eacaea5db9e91d3

I've added it here as an attachment too, it fixes the problem, and it starts booting instantly.
