Thanks. Sounds like the acpi code in RH is not as good in this specific regard as kernel.org compare version tags for acpi code for both kernels in /usr/src/linux-2.6.*/include/acpi/ /usr/src/linux-2.6.*/arch/i386/kernel/acpi (use locate acpi to find the ones I missed). "acpi" is new enough that there has been a lot of learning associated with it by BIOS and OS folks alike. If you are loosing 30 min in and hour then half the clocks tick interrupts are being lost or some other screw up. If the plain linux kernel contains 'newer' acpi code and that code fixes your problem you might file a bugzilla requesting that it be pulled into FC2. -- T o m M i t c h e l l /dev/dull where insight begins.
