Reason: The i386 kernels have been compiled with HPET support but without RTC emulation support (CONFIG_HPET_EMULATE_RTC; HPET: High Precision Event Timer, see Documentation/hpet.txt). And at the moment CONFIG_HPET_EMULATE_RTC requires the rtc driver to be compiled in: Quoting arch/i386/Kconfig, arch/x86_64/Kconfig (linux-source-2.6.18): : config HPET_EMULATE_RTC : depends on HPET_TIMER && RTC=y Workarounds (both tested successfully): 1. boot with hpet=disable 2. build the kernel with CONFIG_RTC=y Regards, Norbert -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
