Hmmm, then I cannot get the ec access log for hang case?! acpi_hw_low_level_read(8, data, &ec->common.data_addr); ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Read [%02x] from address [%02x]\n", *data, address)); Does it mean we need to slow down acpi_ec_intr_read/write ? Could you try to insert acpi_os_stall (100) after ACPI_DEBUG_PRINT statement both in acpi_ec_intr_read/write. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
