Date: Fri, 24 Aug 2007 14:42:55 +0200 From: Felix Homann <fexpop@...inehome.de> To: linux-kernel@...r.kernel.org Subject: Regressions w.r.t. suspend behaviour in recent kernel versions Hi, I've been experiencing several problems with s2ram/s2disk with recent kernels (mostly starting with 2.6.19): 1. s2disk won't work without the nolapic kernel option. I didn't have to use that option with kernels < 2.6.19. I only found out that I need this option with the kind help from Rafael Wysocki. Unfortunately, using the nolapic option raises new problems as I'm getting these warnings at boot time (with kernel 2.6.23-rc2): ++++++++++++++++++++++++++++++++++++ Aug 9 00:22:13 jawaka kernel: EXT3-fs: mounted filesystem with ordered data mode.

Here are the last lines of the kernel output: EIP: [<c01127fd> lapic_nmi_suspend+0x1d/0x30 ss:ESP 0068:c1ae3ec8 Kernel panic - not syncing: Attempted to kill init! Rafael advised me to post directly to the LKML on this issue and so I do. You can follow the whole discussion with Rafael here: http://sourceforge.net/mailarchive/forum.php?thread_name=46A9A9A8.2070209%40onlinehome.de&forum_name=suspend-devel http://sourceforge.net/mailarchive/forum.php?thread_name=200708062038.41452.rjw%40sisk.pl&forum_name=suspend-devel 2. s2ram won't work with kernels > 2.6.18 if the fglrx module is loaded. Please, don't stone me for using the fglrx driver, without it I couldn't suspend at all. Unfortunately, I'm stuck to kernel 2.6.18 at the moment since it's the last kernel that would suspend to ram with the fglrx module loaded. With more recent kernels the system will hang with "Suspending console(s)". 3. Even with the 2.6.18 kernel sound won't work after suspending to ram. I don't know when this started, but I know that this has not been an issue in the past. Please, let me know what additional information you might need.
