Bug#542275: rtc-generic not working on Apple PowerBook G4
Package: linux-image-2.6.30-1-powerpc
Version: 2.6.30-6
Severity: important
When I boot my G4-based laptop, the hw clock can't be accessed and the system
time ends up being the epoch for the platform Jan 1st, 1904.
Switching back to 2.6.26 fixes the problem. Although CONFIG_RTC_DRV_GENERIC
was compiled in in July, it seems the switch from rtc-ppc to rtc-generic
doesn't work, at least on my system. Another Debian PPC user reports the
same breakage in his G3.
2.6.26 from lenny:
[ 7.800992] platform ppc-rtc.0: rtc core: registered ppc_md as rtc0
[ 7.864990] platform ppc-rtc.0: setting system clock to 2009-08-18 18:37:53 UTC (1250620673)
Latest 2.6.30 from unstable:
[ 6.473202] rtc-generic rtc-generic: rtc core: registered rtc-generic as rtc0
[ 6.533547] rtc-generic rtc-generic: hctosys: unable to read the hardware clock
Simon Raven, from #debianppc, has a working kernel which after config
inspection seems to differ only in the CONFIG_RTC_INTF_DEV_UIE_EMUL=y setting,
which is not enabled in Debian.
