           Summary: Missing (important) thermal zone on HP tc4200
           Product: openSUSE 10.2
           Version: Final
          Platform: i686
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Kernel
        AssignedTo: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx
        ReportedBy: jbr.1@xxxxxxx
         QAContact: qa@xxxxxxx


My HP tc4200 had no ACPI problems with SuSE 10.1.
But now after installing (from scratch) openSUSE 10.2 I got temperature
problems. Obviously a thermal zone is missing and the system overheats sooner
or later.
I've already installed:
ftp://ftp.suse.com/pub/projects/kernel/kotd/10.2-i386/SL102_BRANCH/kernel-default-2.6.18.5-SL102_BRANCH_20070220193246.i586.rpm
I will attach dmesg and acpidump.

The interesting part of dmesg:

ACPI: read EC, IB not empty
ACPI: read EC, OB not full
ACPI Exception (evregion-0424): AE_TIME, Returned by Handler for

Obviously "TZ1" is missing:

# ls /proc/acpi/thermal_zone/
TZ2  TZ3  TZ4



Things look much better using
ftp://ftp.suse.com/pub/projects/kernel/kotd/10.2-i386/SL102_BRANCH/kernel-vanilla-2.6.18.5-SL102_BRANCH_20070220193246.i586.rpm

Still some error messages, but the thermal zone is there and seems to be
working correctly.
