Hi The problem is elsewhere. ACPI code is OK. Maybe the SMM mode is into a play, or i2c hw problem might be too. Can you recompile the kernel with i2c debugging on? (for i2c-i801) module? Does the errors occcur right after start, or they are all of sudden? if you unload the w83793 driver but leave i2c-i801 driver loaded and do some script like: while true ; do i2cdump -y 0 0x2f sleep 5 done You will get errors too? Jean, maybe we should move this to i2c ml? Rudolf
