Warning: "lpc_ich: Resource conflict(s) found affecting iTCO_wdt"
ACPI OpRegions are conflicting with the same I/O region used by the lpc_ich driver for the Intel TCO (Total Cost of Ownership) timer (iTCO_wdt, this is a watchdog timer that will reboot the machine after its second expiration). According to Intel Controller Hub (ICH) specifications, the TCO watchdog has a 32 bytes I/O space resource. ACPI OpRegions in the DSDT frequently reserve this TCO I/O space because they require access to bit 9 (DMISCI_STS) of the TCO1_STS register of the TCO. I believe that this bit is not used and is never used by the lpc_ich TCO driver, so the risk of conflict is zero. The warning occurs because ACPI has reserved this I/O region and the lpc_ich driver also wants to access the TCO registers but detects these are already reserved. However, I believe that there is no real conflict to worry about. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027370 Title: lpc_ich: Resource conflict(s) found affecting iTCO_wdt To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1027370/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
