FreeBSD X.Y.net 9.0-STABLE FreeBSD 9.0-STABLE #0: Fri Jan 20 20:52:52 CET 2012
r...@x.y.net:/usr/obj/data/usr/src/sys/COMMON-AMD64 amd64
>Description:
The acpi_ibm kernel module does not include the ID used by newer Lenovo Laptops
(basically, "IBM0086" was replaced by "LEN0086"). Adding the new string to the
ibm_ids struct in acpi_ibm.c allows the driver to attach and work properly.
Tested during daily use on a ThinkPad W520 running 9.0-stable AMD64 since Nov
2011.
>How-To-Repeat:
Try "kldload ibm_acpi" on e.g. a Lenovo ThinkPad W520, the driver will not
recognize the ACPI ID.
>Fix:
Replace line 293 of
