 I can reproduce this problem with FreeBSD 6.1-RELEASE on my IBM
 ThinkPad X31.
 
 Whenever I attempt to access the hardware through ACPI, either by
 powering down (shutdown -h now), rebooting (shutdown -r now), loading
 the acpi_ibm kernel module (kldload acpi_ibm), pressing the volume
 keys etc, the system locks up with no sign as to why.
 
 I have found many postings on various mailing lists (see e.g. [1] and
 [2]) that suggest using PS2.EXE from IBM to disable the secondary IDE
 channel, but I have yet to find a way to try that as I do not have
 access to a Microsoft Windows environment.
