Ok, nevermind then, I misread things in the brief browsing I did of CHANGES.txt in the ACPICA distribution. Do you have any ideas why an older version of ACPICA would accept his FACS, but the more recent versions are now choking on it? Did the in-kernel version not verify checksums on FACS until recently? It seems that acpidump has always reported that the table is corrupt, even with the older ACPICA distribution. > > -----Original Message----- > > From: owner-freebsd-acpi@freebsd.org [mailto:owner-freebsd- > > acpi@freebsd.org] On Behalf Of John Baldwin > > Sent: Tuesday, November 29, 2005 1:47 PM > > To: David Kelly > > Cc: freebsd-acpi@freebsd.org > > Subject: Re: Worked in RELENG_5, fails in RELENG_6 > > > > On Tuesday 29 November 2005 04:19 pm, David Kelly wrote: > > > On Tue, Nov 29, 2005 at 02:52:34PM -0500, John Baldwin wrote: > > > > On Monday 28 November 2005 10:46 pm, David Kelly wrote: > > > > > Downloaded and FLASHed BIOS from A06 to Dell's latest, A09 this > > > > > evening.
