I have one notebook that is failing to resume after suspend to ram. I've filled a bug report back on the 2.6.41 days:
https://bugzilla.redhat.com/show_bug.cgi?id=787299 The issue is that trying to resume after suspending to ram freezes the computer. The resume starts well, but then it hangs. Yesterday I found that this may be related to VT-d / x2apic. If I disable VT-d on the BIOS, suspend / resume works fine. If I enable VT-d and pass nox2apic as boot parameter to Kernel suspend and resume works fine. I would like some pointers to fix this issue. Can you help me? Only when I have VT-d enabled, dmesg gives me additional output: [ 0.023913] IOAPIC id 2 under DRHD base 0xfed91000 IOMMU 1 [ 0.024080] Enabled IRQ remapping in x2apic mode [ 0.024081] Enabling x2apic [ 0.024082] Enabled x2apic [ 0.024087] Switched APIC routing to cluster x2apic. The notebook is Toshiba R830-10p with i7-2620M.
