Currently it looks like the posting has not been opened to public yet? I hope that IBM will provide a patch or that we can assist in creating a work around for the buggy bios. I know several friends who are running Linux on their A31's. Currently we all stick to kernel 2.4.19 + acpi-20020918 patch. This combination provides at least some support for ACPI. Thanks to the hard-working acpi-development team! Dom -------- Topic: ACPI Linux (1 of 1), Read 10 times Conf: ThinkPad A20,A21,A22,A30,A31 From: bartenst Date: Thursday, January 02, 2003 03:07 PM Hi all! I am successfully running Gentoo Linux (http://www.gentoo.org) on my new A31. Unfortunately ACPI is not getting initialized properly with the new acpi-patch from 20021212 ( + vanilla 2.4.20). I consulted the acpi developers (http://acpi.sf.net) who told me that the problem is the buggy BIOS! Is IBM aware of that problem and are there any ongoing efforts to solve this problem? Thanks! Dom p.s. http://marc.theaimsgroup.com/?l=acpi4linux&m=103643408113691&w=2 summary: "In short, ECDT -> EC_ID is supposed to be the full path name of your EC device in ACPI Namespace like "\_SB.PCI0.LPC.EC", but __NOT__ in your BIOS. You can work around your problem by adding hack code, but it makes OS code dirty to save broken BIOSes and it allows BIOS vendor not to fix their problem." ---------- On Thursday 02 January 2003 22:31, you wrote: > > sorry - i did not see Andy Grover's reply to Sandro earlier on.
