Locks on boot at 'Setting system clock to hardware clock...'

I've got the latest benh codes, and by using posts in this forum have gotten this far, but no further.

Trying to run linux on a Titanium Powerbook G4 500, and every time I boot from the compiled kernel, it locks at the:

'Setting system clock to hardware clock [Local Time]...'

section of the boot.

I've tried enabling and disabling the enhance RTC in the kernel, and am at a loss. Does anyone have a working kernel config for a TiPowerbook G4 500 that they could post, so that I could compare?

what did you link /etc/local time to ?

and did you edit your rc.conf file? looks like you did, but just checking

Well, I got past the lock when setting the system clock, and local clock, on startup and shutdown, however I've had to disable '/dev/rtc' and 'Enhanced Real Time Clock' in the kernel config before compiling.

However, I assume this shouldn't be happening, anyone have a config from a similar machine (powerbook g4 type)?

Just to give back to the forum, I figured out what the problem was:

If you set "CONFIG_PPC_RTC=y" in your kernel config, it locks (on my machine, haven't tested it elsewhere), however, if you set "CONFIG_PPC_RTC=m", then it works.

WOOHOO!

Now, on to X.

Thank you for giving back - I was trying to figure that one out for hours.

This part is clearly documented in the install guide

enchanced RTC support does _NOT_ work on ppc kernels, never has and likely never will. Having it as a modules (M) is probably also a bad idea. Turning it right off is best. If anything tries to load that module your system will lock hard.

Yes, I noticed that in the documentation, and I had "Enhanced RTC" disabled and "Support for /dev/rtc" enabled, but I compiled it into the kernel proper which was the source of the problem - and not mentioned in the documentation. And thats the "Support for /dev/rtc" from general setup that would not work if not compiled as a module, not "Enhanced rtc", just in case there is any confusion.

ahh hmmm

the /dev/rtc shoud work compiled into kernel (in theory)... it has never given me problems, even on some of my more exotic hardware.

I'll have to keep that in mind, thanks
