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.
