My system doesn't hang even with the stack trace. I posted another patch on the bug page. It widens the BOOTFB resource to match the PCI BAR instead of making it busy. With the new patch, nvidiafb doesn't report that the resource is busy, it reports unsupported hardware, which is true. Old patch: nvidiafb 0000:01:00.0: BAR 3: can't reserve [mem 0xf0000000-0xf1ffffff 64bit pref] nvidiafb: cannot request PCI regions New patch: nvidiafb: Device ID: 10de0ffc nvidiafb: unknown NV_ARCH I'll send the patch to x86-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org, it's clearly not an nvidia issue. -- Regards, Pavel Roskin
