Date: Mon, 12 Jul 2010 19:59:54 -0700 From: Yinghai Lu <yinghai@...nel.org> To: Ingo Molnar <mingo@...e.hu>, "H. Peter Anvin" <hpa@...or.com>, Thomas Gleixner <tglx@...utronix.de>, Suresh Siddha <suresh.b.siddha@...el.com> CC: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: tip/master broken with x2apic and kexec tip/master: system1: BIOS enabled x2apic, first kernel boot well, and when kexec second kernel will cause system instant reboot. system2: BIOS not enable x2apic, first kernel boot well and enable x2apic, and kexec second kernel well. but when kexec third kernel will case system instant reboot. linus' tree is ok. but for system2 if boot with nox2apic ,intr-remaping off, iommu off, the kexec loop test will pass. the problem looks start in recent two or three weeks. Any idea? bisecting will take a while, because the system post take a while everytime.
