Kernel boot hangs after "Real Time Clock" line
Hi everyone, I'm new here so I'm not quite sure on where problem posts go re. booting, but here goes anyway...
I've recently been trying to get a 2.6.11 kernel working on my home PC. Before it was running 2.4.27-speakup (debianised kernel). I have compiled a few kernels before, but I've never got so stuck as I have now...
The first problem I had, which is now fixed, was the fabled "VFS: Unable to mount root filesystem..." error that I see has a few topics in this forum. However, I managed to fix that by changing SATA operation in my BIOS (long story).
However, now my boot process gets about ten lines further on, to the "Real Time Clock Driver 1.12" line, and then freezes. There's no error message.
Searching the 'net seemed to suggest that SMP may have issues with this, however I had MTRR support compiled in, and all the other things that other websites said were required. This computer in fact has before ran a 2.6.10 kernel with SMP just fine. And just to prove it, I took SMP support out and recompiled and booted, and sure enough it hanged at the same place.
Does anyone know why it would hang there?

I don't know how to get the output of dmesg for the failed boot attempts - if someone else knows tell me and I'll post that too.
Thank you very much for your time and help

Can you say if your new kernel is capable to load RTC?
If it doesn't, can you check on your kernel configuration if you added that support?
It seems that your P4 processor is not HT. Can you confirm that?
If not, check on you kernel configuration the SMP support and, if your processor ain't HT, just disable it.
Regards!

Is this "HPET Timer support"?

The processor *is* HT - it's just that the stock kernel I got off the debian CDrom was 2.4.27-speakup, which doesn't have SMP support compiled in, so cat /proc/cpuinfo doesn't report the second CPU. Originally Posted by mcm

Thanks for your help, I'll try looking around the RTC options again...

All right, so your processor is HT. I asked, exactly because of /proc/cpuinfo results.
So, don't forget to turn on SMP support on your kernel!
About the RTC:
Go to APM (Advanced Power Management BIOS Support) and check the option RTC stores time in GMT.
That might help.

I compiled again with APM=m, and the RTC is GMT as Y (even thought the clock was in fact localtime. That kernel hanged also.
But then I did a "make-kpkg clean" and compiled it with APM=Y instead of m (and still with the RTC is GMT as Y), and it worked!
It got past the first stage fine, but hanged when it tried to start the X server. Though I am convinced that this time I can fix that error - I'm trying to use the fglrx driver for my Radeon and I think I know what's wrong.
If I have any more trouble I'll post again.
Thanks very much for the help!

All right, I'm glad that your new kernel is up and running!
To compile your own kernel is an art!
Regards!
