[ale] hwclock hangs

[Joe Steele]

The following may [not] help in diagnosing your problem:

The kernel source includes a test program in 
linux/Documentation/rtc.txt which you could compile and run to check 
the functionality of /dev/rtc.  Also, check the contents of 
/proc/interrupts (IRQ 8) before and after running the test program to 
see if the rtc is generating interrupts.  

You could also look at the contents of /proc/driver/rtc  (to see if 
the RTC is keeping time).  

An strace of hwclock may also provide some clues.

Subject:	[ale] hwclock hangs

I have scratched a hole in my head with this one.

I have an ASUS A7V133. I have been running SuSE 7.1 since it first came 
out. Yesterday, I went and bought SuSE 8.0. I go to install it, and I 
fiddled with the partitions to get it the way I liked it, but I made a 
mistake and got /var and /usr confused and the installation was screwed. 
No worry, I have a backup of my home directory, so nothing important was 
lost.

I go to reinstall it, and during the probing, it hangs.

I look at another console to see what is happening - it turns on hwclock 
is hanging. Sure enough, hwclock hangs whenever it is called.

I run hwclock -D and it says it hangs after it looks for a clock tick. 
The clock tick never comes.

I can get aninstallation running, but every time it boots, init hangs on 
the CMOS clock stage. Hitting CTRL-C will get it to continue. And it 
doesn't continue quite the way I would like it to.

I've tried installing older kernels, but the problem persists. Which 
makes me think it is something to do with my motherboard. Do you think 
the SuSE 8.0 probing is setting something off and turning off the clock 
or something? How can I tell? How can I prevent it from happening?

Someone suggested I replace the battery. Replacing the battery helped 
for a few times, but then it started hanging again. Of course, it was an 
old battery, but it wasn't that old. I'm going to go get a newer battery 
unless I can think of something else.

Any suggestions?

Jonathan
