system clock is too slow

[Gang Qin]

The problem is there is no problem if the system is power-off. And also 
there was no problem before I changed from RH9 to FC2 one week ago. 
Maybe you could help me to figure out what is wrong. From 'cat 
/proc/interrupts' I can see 'ERR  5', maybe there is some clue? I am 
attaching some information at the end of this email, thanks.

It is a hp pavilion ze4400 (or compaq presario 2100)  with Mobile 
Intel(R) Celeron(R) CPU 2.20GHz,  inner QSI CD-RW/DVD-ROM SBW-241,  
inner ATA DISK drive 5400 40G

After init 1, I found my system clock only passed 31 min for an hour.

results of "cat /proc/interrupts" are in the bottom.

There were no problem before I change from RH9 to FC2. The FC2 is a 
fresh installation. I may try the freedos later. Thanks.
