Hyper-Threading in Linux?

Hey thanks man, seems like basically all I needed was to include ACPI and it woulda probably worked. I will be compiling me a kernel soon my man :-D

Please tell me all about how sweet the machine is running afterwards - I'm considering getting one for my gf.

Hope you get it to work.

I think I read something about applying a patch.

Ok I am able to compile and make it see dual cpus :-D Im using 2.4.21, but Im having a weird issue:

[root@blazin /]# lsmod
Module                  Size  Used by    Not tainted
[root@blazin /]#

As you can see, no modules at all.....My network works , havent had a chance to test video since I am sshed in remotely doing all this right now.

Also it only mounts my ext3 partitions at boot up, none of my FAT32 partitions. But I can mount those manually once booted up........

What could cause it to have no modules and whatnot? I did make modules and make modules_install and depmod -a. Nothing.....

But on one cool note:

Only thing I can think of is that perhaps you compiled the needed stuff as part of the kernel, instead of as modules. That would be the only way you'd have support for things and not have modules.

I don't think it matters much.

Regarding the fat32, what happens if you do modprobe vfat?

[rick420]

Also I figured this out by just loading my mandrake config file and removing crap I didnt need. Mandrake seems to be picky on what you compile in and what is modules and it makes me use an initrd to work properly.

Only thing that seems wrong now is that it still doesnt mount any FAT32 partitions at bootup, but I can mount them just fine afterwards....

That's strange. It worked before, right? What's your /etc/fstab look like?

PS: How beautifully does that thing sing? I had a small...ahem...issue (read: fire) with my cpu a few days back and hoped the mb was lost so I could get a similar setup, but alas...'twas only the CPU. $50 later I'm still sitting at a 1GHz T-Bird.

Yea its still kinda strange....Every single kernel I have compiled I enabled SMP and it enabled both CPUS no probs, but like I said none of my FAT32 will mount at boot, and a few other errors regarding NFS , but nothing major ..........until I try to use X.......

First off, the default drake kernel boots with a GUI image thing, I disabled that and added the lilo parameter, vga=ask, to my lilo.conf. Thing is the best resoution I can choose is like 152x50. Which looks liek trash. Worst part is that once I try to use X with any new kernel I have tried, my screen goes to garbled colors and i have to reboot.......

SO then I tried Mandrakes official SMP kernel, which works fine, except that it doesnt show 2 cpus.......grrrrrr

BTW, this box still fucking flys, it only takes me maybe 10 mins to fully compile a kernel and reboot into it :-D

try a 2.5.70-mm5 kernel - I think there are some issues with HT and 2.4 in some vendor kernels.

Did you applied the HT patch they talk about in the mailing list link?

What kind of video card are you using?
