Hello everyone (again),

I just realized these messages have not been going to the list, so I am
replying to the list in hope of getting more answers.

To add to the messages below, I just opened up my computer and found out
that my motherboard is:

American Megatrends P4VMM2

The BIOS shows the following serial number at the boot screen:
62-0124-001131-00101111-040201

It has an Award (AMIBIOS) BIOS

Thanks in advance.

| | You shouldn't have any problems compiling the kernel.  Especially if
| | you're using RH9 (if I recall correctly).  Compiling the kernel is
| | actually a common test people use to test the stability of an
overclocked
| | computer.  If compiling fails, it usually means that the voltage
settings
| | aren't stable or the memory isn't keeping up.
| I am inclined to think this is the reason.  I have noticed that not only
| compiling, but other apps too have started randomly crashing.
|
| I may even know how it happened: after my mother-board was replaced, the
| CPU front-side bus was set to 100MHz (1.8GHz CPU).  I tried switching
| the FSB speed to 133MHz (so it runs at 2.4GHz like it should).
| Unfortunately, I didn't know where the DDR jumper was so I went back to
| store and had the guy there take a look at it.  He changed the DDR speed
| and said it's OK now.  Maybe he forgot the voltage.
|
| Where can I get the info about the appropriate voltages for my
| CPU/Motherboard.  The Motherboard has a VIA everything, and Award bios,
| and I am not sure of the actual make. The CPU is a 2.4GHz Pentium 4.

| | Have you ever had any previous problems with your memory sticks?
| No.
|
|
| | Just to make sure it's not a CPU, Memory, or Motherboard problem, you
| | could try underclocking your CPU to something lower than the "vanilla"
| | setting.  Ensure that the processor has plenty of "error room" to work
| | with.  Try using these (albeit slower) settings, and try compiling the
| | kernel again.  If it succeeds this time (or if your computer stops
| | crashing), then maybe there is something with your CPU settings you need
| | to twiddle.
| Come to think of it, the kernel compiled fine when I was running at
| 1.7GHz until I tuned it up.
|
| | Are you using the Binary Only NVIDIA drivers?  I experience the freeze
| | problem with VT switching to/from X sometimes when using the binary
| NVIDIA
| | drivers, though I have no problems with resolution switching.
| No.  I have a Radeon 7000 and use the normal kernel radeon.o module.
| The problem is probably the same voltage setting issue. Maybe the
| voltage on the AGP bus?  I tried going into Windows and switching the
| resolutions a few times; seemed to work fine.
|
| | Do your XFree or Kernel logs show any error messages (looking at them
| | after a reboot)?  If it's a X or driver crash, maybe the kernel had just
| | enough time to log something....
| No. Nothing interesting in either log.  Maybe just this one thing in
| XFree86.0.log:
|
| drmOpenDevice: minor is 0
| drmOpenDevice: node name is /dev/dri/card0
| drmOpenDevice: open result is -1, (No such device)
| drmOpenDevice: open result is -1, (No such device)
| drmOpenDevice: Open failed
| drmOpenDevice: minor is 0
| drmOpenDevice: node name is /dev/dri/card0
| drmOpenDevice: open result is -1, (No such device)
| drmOpenDevice: open result is -1, (No such device)
| drmOpenDevice: Open failed
| drmOpenDevice: minor is 0
| drmOpenDevice: node name is /dev/dri/card0
| drmOpenDevice: open result is 8, (OK)
|
| Seems like it keeps missing the card, although it may just be the delay
| from loading the radeon.o module automaticly.
