Intel Core i7 and X58 experience?

[JunGL]

I'm using 2.6.27-9-generic

Do you use 2.6.27 or 2.6.28 kernel?

I installed a system based on a Gigabyte EX58 deluxe but for some reason, I am not getting eth0 or eth1 to show up in ifconfig. What's odd is that I had it working randomly once but after restarting I no longer have access to LAN. Any ideas?

Thanks! It looks like MCE is enabled:

config-2.6.27-9-generic:CONFIG_LIRC_MCEUSB=m
config-2.6.27-9-generic:CONFIG_LIRC_MCEUSB2=m
config-2.6.27-9-generic:CONFIG_X86_MCE=y
config-2.6.27-9-generic:CONFIG_X86_MCE_AMD=y
config-2.6.27-9-generic:CONFIG_X86_MCE_INTEL=y

It looks like it was really a bios problem. I updated my bios with the bios taken where you said and now no more MCE get logged.

To see if you have MCE enabled, you can go to the boot dir and do "grep MCE config*"(in that dir you should have a file called config-"something") and look for the things I posted on the previous message.

I am running a stock Ubuntu kernel, 2.6.27-9. I'm not sure if MCE is enabled, but dmesg | grep -i machine does not find anything (also nothing in /var/log/messages), so I guess not.

I have been running the computer quite a bit (I am using it now) so if an MCE is very bad, probably I'm not getting any?

Also, I replied in another message that I got my F4K BIOS update from a tweaktown board, but I think my post got sent for moderation because of the URL. Hopefully it shows up soon.

MCE = Machine Check Exception(very very bad, it usually means an hardware problem)

In this particular case though, it happens only at boot, so it may be related to a bug in the bios, which causes the MCE at boot POST time.

To search for it, first you need to have a kernel with MCE enabled. If you use a debian kernel, that's good. If you don't know, just do a "grep MCE config-file", where config-file is the config file used to build your kernel. You should see this :
CONFIG_X86_MCE=y
CONFIG_X86_MCE_INTEL=y
Then just boot your system with that kernel, wait ~10 minutes(even a lot less should suffice, but just to be sure), then on root terminal type "dmesg | grep Machine". If you get something like "Machine check events logged", then an MCE got logged. depending on the distro(and the log daemon), you may also try "cat /var/log/messages | grep Machine", but just using dmesg should suffice.

Another thing, have you ever heard the cpu fan in Linux? I haven't, not even when I touched more than 70?C. I guess that's because this motherboard and cpu is still not supported. I can get the readings of the cpu sensors, but the system doesn't seem to react to to the temperature readings.

I have a UD5, but my CPU is a 965. My kernel is 2.6.27-9 x86_64. If you tell me what an MCE is and what your log message looks like, I will check my logs to see if I have it.

The 'W83667HG' is the sensor chip the Asus board has. Your mb probably
has a different sensor chip. I am basically using a 'W83627EHF' module
for now because it is very similar. 'modprobe w83627ehf force_id=0x8860'.
A patch has been added to kernel-2.6.28-rc8 to add support for the
w83667hg module. The lm_sensors repo now has a beta version that
allows coretemp to be recognized as the Core i7 temp module.
Sensors-detect has also been patched to detect w83667hg.

Thanks for the explanation. Does anyone know what sensor chip the Gigagbyte EX58-UD5 motherboard uses? I've looked at lspci and lshw and either it is not there or I am not recognizing it.

I'd like to check any motherboard temperature sensors I can, since I am using a CPU cooler that blows air parallel to the motherboard, and I am wondering whether the motherboard chipsets are receiving adequate cooling.

Does anyone else have an I7 920/940 with a Gibagyte GA-EX58-UD5? I have one and I've been using Linux 64bit in it for some days now. There seems to be some problems with this hardware configuration, because I get an MCE logged every time I boot, but never more after the boot(at least for what I've seen so far). I've posted about this on the lkml and I received emails from other 2 people who have the same problem. The MCE gets logged only on kernels >= 2.6.27(64 bit).

I have a UD5, but my CPU is a 965. My kernel is 2.6.27-9 x86_64. If you tell me what an MCE is and what your log message looks like, I will check my logs to see if I have it.
