From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matthew Garrett Subject: Resume failing in get_cmos_time() Date: Mon, 19 Jul 2004 13:22:07 +0100 Sender: linux-kernel-owner@vger.kernel.org Message-ID: <1090239727.7459.10.camel@tyrosine> Mime-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit Return-path: To: acpi-devel@lists.sourceforge.net, linux-kernel@vger.kernel.org List-Id: linux-acpi@vger.kernel.org On around 20% of ACPI resume attempts, the resume hangs during time_resume(). I've traced this down to the get_cmos_time() call - a printk before that appears, one afterwards doesn't. The rest of the time, resume works correctly. Interestingly, this only seems to happen if I use the patch from http://bugzilla.kernel.org/show_bug.cgi?id=2643 or a similar one for the IO-APIC. Does anyone have any idea why this might result in this sort of failure mode? I'm considering just removing the call for now and resetting the clock from userspace. -- Matthew Garrett | mjg59@srcf.ucam.org
