I think so, if not I will use acpi@linux.intel.com again. I didn't know this one is registered, will always add this when I get such reports from now on then. I just checked, the HP dv8000 from Antonis and the HP Pavillion DV5175EA from Sandro have exactly the same DSDT (only one mem region is declared with a different value), so you suffer the same problem for sure. Maybe someone of the Intel guys can shed some light on the ACPI spec concerning the _REG method (this is about _REG method, chapter 6.5.4 ACPI spec 3.0 on page 228/229). My question is whether _REG(3,0) (Embedded Controller, disconnection handler) must be called after EC driver has been initialised or (this is what I think and kernel currently seems to do and then it's a BIOS bug) whether it only must be called after EC driver gets unloaded (therefore never or only at machine shutdown time). Ubuntu must have a patch included that avoids that EC's _REG method is invoked with parameters _REG(3,1) or they call _REG(3,0) somewhen. I didn't find a nice way to access ubuntu kernel package files I try to find out which patch could workaround/fix this issue in ubuntu... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
