Get the same issue with the latest kernel 3.5.0-6

[dino99 (9d9)]

dmesg3.5.0-6

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.5kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Colin Ian King (colin-king)]

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.

[Colin Ian King (colin-king)]

Warning: "lpc_ich: Resource conflict(s) found affecting gpio_ich"

This again is because ACPI OpRegions conflict with the same I/O region used by the lpc_ich driver, this time for the GPIO region. Again, I don't believe this is an issue to worry about.

[Colin Ian King (colin-king)]

I don't think this are bugs per-se. The lpc_ich driver uses these I/O regions that are already reserved by ACPI OpRegions and they seem to co-exist OK without any issues. The warnings are alarming, but can be ignored. There's nothing to fix.
