I'm using CentOS 6.3 x86_32 guest running on VMware Workstation 6.5.5 for
Windows XP x86_32 host and VMware Player 4.0.5 for Windows 7 x86_64 host.

Kernel version is 3.9-rc1 x86_32. This bug can be triggered only when the
guest has little RAM such that /proc/meminfo reports that HighTotal == 0.
Config is at http://I-love.SAKURA.ne.jp/tmp/config-3.9-rc1-acpi .

I don't know why but changing kernel config to CONFIG_ACPI=n
( http://I-love.SAKURA.ne.jp/tmp/config-3.9-rc1-noacpi ) solves this bug.
Well, should I run bisection on ACPI code?

Regards.
