I got the following problem after my FC3 install:
Losing too many ticks!
TSC cannot be used as a timesource.
Possible reasons for this are:
You're running with Speedstep,
You don't have DMA enabled for your hard disk (see hdparm),
Incorrect TSC synchronization on an SMP system (see dmesg).
Falling back to a sane timesource now.
Seems I had this problem when compiling a custom kernel for an
a7n8x board recently. hdparm couldn't enable the dma either. It
finally worked after adding the correct IDE driver (amd/nforce)
for that mobo. Until I corrected the problem disk performance
was quite poor.
I have ide=nodma in the boot parameters, since I was not able to
complete the install with that parameter.
If I try to take this parameter out of the grub.conf, I get the below
and the machine does not boot:
You may need to compile a custom kernel with the correct driver for
your motherboard. Or perhaps get try an updated kernel.
