--- Comment #21 from Feng Tang <[email protected]> 2012-10-02 03:59:38 --- commit a0e35322910555e20e9eced3f050a76c7b3a1f92 mfd: lpc_ich: Fix a 3.5 kernel regression for iTCO_wdt driver There are many reports (including 2 of my machines) that iTCO_wdt watchdog driver fails to be initialized in 3.5 kernel with error message like: [ 5.265175] ACPI Warning: 0x00001060-0x0000107f SystemIO conflicts with Region \_SB_.PCI0.LPCB.TCOI 1 (20120320/utaddress-251) [ 5.265192] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 5.265206] lpc_ich: Resource conflict(s) found affecting iTCO_wdt The root cause the iTCO_wdt driver in 3.4 probes the HW IO resource from LPC's PCI config space, while in 3.5 kernel it relies on lpc_ich driver for the probe, which adds a new acpi_check_resource_conflict() check, and give up the probe if there is any conflict with ACPI. Actually the same check could be removed for the gpio-ich in lpc_ich.c, but I'm not sure if it will cause problems. This is the commit log, as it pointed out, it only fixes the iTCO_wdt problem, and doesn't touch other warning for "gpio_ich". If anybody see problem with this "gpio_ich", please create a new bugzilla to trace that. thanks, -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
