FreeBSD here is 6.1-STABLE i386 (around May 7 2006) on IBM ThinkPad T42 (2373-5TU). > >Description: > The machine will crash if any of the volume buttons are pressed. > The machine will also crash when trying to load the ibm_acpi driver Did you mean acpi_ibm kernel module?

Loading acpi_ibm module itself also did not cause crash. - Parv -- 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. [1]: http://lists.freebsd.org/pipermail/freebsd-acpi/2004-November/000870.html [2]: http://lists.freebsd.org/pipermail/freebsd-current/2004-January/019435.html -- Henrik Brix Andersen <henrik@brixandersen.dk> I managed to get hold of an MS-DOS environment for running "PS2.EXE IDE2 Disable" from IBM [1] on my IBM ThinkPad X31 as adviced in the previously mentioned mailing list posts. After disabling the secondary IDE bus I can no longer reproduce the problem described here. Disabling the seconday IDE bus will, however, also make it impossible to use a secondary HDD or CDROM drive in an UltraBay docking station, so this is not an optimal solution - only a work-around. Footnote: this problem doesn't exist with other operating systems such as GNU/Linux, which indicates that it is a problem that can be solved in software.
