Message-ID: <20070630030343.31711.qmail@science.horizon.com> Date: 29 Jun 2007 23:03:43 -0400 From: linux@...izon.com To: linux-kernel@...r.kernel.org, linux-pm@...ts.linux-foundation.org Cc: ak@...e.de, bk@...e.de, hpa@...or.com, linux@...izon.com, michal.k.k.piotrowski@...il.com Subject: Re: 2.6.22-rcX Transmeta/APM regression Okay, after a ridiculous amount of bisecting and recompiling and rebooting... First I had to find out that the kernel stops booting as of bf50467204: "i386: Use per-cpu GDT immediately on boot" (With theis commit, it silently stops booting. The GP fault I posted earlier comes a little later, but I didn't bother finding it.) and starts again as of b0b73cb41d: "i386: msr.h: be paranoid about types and parentheses" However, one commit before the former suspends properly, and the latter fails to suspend (exactly the same problem at get_fixed_ranges+0x9/0x60), so I had to bisect further between the two, backporting the msr.h changes across the msr-index.h splitoff. Anyway, the patch which introduces the problem is the aptly named 3ebad: 3ebad59056: [PATCH] x86: Save and restore the fixed-range MTRRs of the BSP when suspending 2.6.22-rc6 plus that one commit reverted successfully does APM suspend (and resume) for me. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
