[2.6.27.4-5 stable regressions] Kernel boot early crash withlow-64k reservation patches

From: Bruno PrÃmont
Date: Tue Dec 09 2008 - 02:42:24 EST

Hi,

On a VMWare (ESX 3.5.0 Update 3) guest we get boot failure at the very
beginning of boot process. (Boot successful with 2.6.27.4, failing with
2.6.27.x where x > 4 or just adding the 5 patches below to 2.6.27.4)

State of config option
CONFIG_X86_RESERVE_LOW_64K=y
or
# CONFIG_X86_RESERVE_LOW_64K not set
does not make any difference.
