Message-ID: <47E052E3.4000107@suse.de> Date: Wed, 19 Mar 2008 02:40:19 +0300 From: Alexey Starikovskiy <astarikovskiy@...e.de> To: Guillaume Chazarain <guichaz@...il.com> CC: linux-acpi@...r.kernel.org, linux-kernel@...r.kernel.org, lenb@...nel.org, Tim Elliott <tle@...ymonkey.com> Subject: Re: ACPI regression in 2.6.25-rc6 (function keys stop working) Hi Guillaume, Thanks for tests, it looks like call_psw_on_capable_devices.patch does not help at all, and we should just revert the offending patch. Sorry for the toruble, Alex. Guillaume Chazarain wrote: > Hi Alexey, > > Thanks for your assistance.
