This is on Acer TravelMate 5730G. re-assign to John, the maintainer of acer-wmi driver. Thanks, Len, for reassigning properly. Now, anyone have any idea how get_maintainer.pl named me and Johannes for acer_wmi.c? ./scripts/get_maintainer.pl -f drivers/platform/x86/acer-wmi.c Carlos Corbacho <carlos@strangeworlds.co.uk> John W. Linville <linville@tuxdriver.com> Len Brown <len.brown@intel.com> Alan Jenkins <alan-jenkins@tuffmail.co.uk> Johannes Berg <johannes@sipsolutions.net> linux-kernel@vger.kernel.org Looks like a bug in the ACPI-WMI driver, not acer-wmi. Probably related to the change for autoloading which added the sysfs interface. Oldřich, can you please attach your DSDT? Created attachment 24271 [details]

Created attachment 24234 [details] dmesg output The boot fails completely (no usable trace) when the acer-wmi+wmi is in-kernel. I've compiled it as module, so here is the trace extract (full trace included): [ 86.439943] WARNING: at fs/sysfs/dir.c:477 sysfs_add_one+0x65/0x7a() [ 86.439951] Hardware name: TravelMate 5730 [ 86.439957] sysfs: cannot create duplicate filename '/devices/virtual/wmi/05901221-D566-11D1-B2F0-00A0C9062910'
