[linux-audio-user] unable to open rtc device

hi list, looking into dmesg i find this strange thing: 'drivers/rtc/hctosys.c: unable to open rtc device (rtc)' kernel configuration file looks like: nowhiskey@murija2:/usr/src/linux-2.6.20$ grep RTC .config CONFIG_RTC=m # CONFIG_RTC_HISTOGRAM is not set CONFIG_GEN_RTC=m CONFIG_GEN_RTC_X=y CONFIG_SND_RTCTIMER=m CONFIG_SND_SEQ_RTCTIMER_DEFAULT=y CONFIG_RTC_LIB=y CONFIG_RTC_CLASS=y CONFIG_RTC_HCTOSYS=y CONFIG_RTC_HCTOSYS_DEVICE="rtc" # CONFIG_RTC_DEBUG is not set # RTC interfaces CONFIG_RTC_INTF_SYSFS=y CONFIG_RTC_INTF_PROC=y CONFIG_RTC_INTF_DEV=y # CONFIG_RTC_INTF_DEV_UIE_EMUL is not set # RTC drivers # CONFIG_RTC_DRV_X1205 is not set # CONFIG_RTC_DRV_DS1307 is not set # CONFIG_RTC_DRV_DS1553 is not set # CONFIG_RTC_DRV_ISL1208 is not set # CONFIG_RTC_DRV_DS1672 is not set # CONFIG_RTC_DRV_DS1742 is not set # CONFIG_RTC_DRV_PCF8563 is not set # CONFIG_RTC_DRV_PCF8583 is not set # CONFIG_RTC_DRV_RS5C372 is not set # CONFIG_RTC_DRV_M48T86 is not set # CONFIG_RTC_DRV_TEST is not set # CONFIG_RTC_DRV_V3020 is not set nowhiskey@murija2:/usr/src/linux-2.6.20$ in the line 'CONFIG_RTC_HCTOSYS_DEVICE' i choosed 'rtc' because in my filesystem there is only '/dev/rtc' and no '/dev/rtc0' or '/dev/rtc1'. anyway, more down in the dmesg there is: 'Real Time Clock Driver v1.12ac Generic RTC Driver v1.07' does this mean that rtc is started successfully or not? the module 'rtc' shows up in lsmod after boot. i hope that someone can help me to clarify what is going on here. cheers, doc
