When you are grasping at straws, just grab all you can. Since you got it to work then I wouldn't think it was software, a failing hardware such as a bad CPU or a bad kernel. Generally if it works on a CD, then it is software. If it also fails from a CD, then it should be hardware. Sounds like yours is a hardware issue but just a compatibility problem, not failure. Maybe check if there is a BIOS update available? Might be worth a shot. Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words!

I'll be using my existing water cooling setup, so no need to worry about that. However, after some research, I've decided to stick with Intel and orders an i7 2600k today. I wasn't sure whether it was worth the extra over the i5, but knew I would only regret it the first time I had to wait for something. I rationalised the cost by getting only 8GB of RAM, but leaving the slots free for another 8GB should I feel the need for it. I am more Intel-biased also, as I always chose Intel for my own boxes. I quickly clicked a new box together in some online configurator, the difference between 8G and 12G wasn't too much, I could get that in by downgrading a bit on the graphics card (which even in the lower version would be much more powerful than the one I have right now). I use 8G now and it rarely gets really to full use. It just doesn't feel too clever to not take one step up when buying new stuff ;-) Very often one looks back a year after and regrets I should have chosen the bigger CPU, more RAM, whatever I will decide the RAM-issue when I order. I just start to compare. 6 cores, yep, sounds good for both gentoo-compile-work and VMs ... The Intel chips are only four cores, but appear to give a lot more bang-per-core, especially with the i7's hyperthreading. yep. That would mean 8 threads w/ i7 (4 real and 4 hyper) vs. 6 real threads w/ amd? I also tend to i7 2600k, some reviews look very good. I will see what your reports tell us :-) Stefan

Storage is a little small. 8GB internal, about 6.3GB available to me, but for $199 I have to say that having a portable reader/movie player that also gives you free video if you're an Amazon Prime member and has apps for playing NetFlix Instant Watch and Hulu+ is really nice. Personally I like the 7 screen format but the device does feel a little heavy. Batteries lasted all day and through the evening. - Mark

[gentoo-user] sdhc card on eeepc701 running gentoo
Hello, I'm having lots of hardware error current when trying to use a sdhc card (transcend 16GB) on my eeepc701.

If it was me, I wouldn't trust it with any data where there is no copies somewhere else. It has problems, I would replace it. Since it is under warranty, just get them to replace it.

I was thinking of reading the details of bind mounting, but decided I spent/wasted enough time trying to have a clean system with all mounting at /mnt. If your suggestion meant that usr would be mounted at both / and /mnt, I don't see that as any cleaner than having it just at /. If the purpose was to document all the mounts by having them at /mnt, I could do that with a symlink ln -s /usr /mnt/usr I still feel it is somehow cleaner to have all mount points be in /mnt, but am cutting my losses. thanks for the suggestion. allan On Nov 16, 2011 5:45 PM, Allan Gottlieb gottl...@nyu.edu wrote: On Wed, Nov 16 2011, Allan Gottlieb wrote: I am reinstalling gentoo on a Dell inspiron 6400 laptop I am (again) using lvm2.

[gentoo-user] LVM and LABELS in fstab
OK. I jumped into LVM. I took my spare drive, put it to use with LVM. Then copied data from my super large drive to it and backed up some to DVDs that wouldn't fit. Then I put the big drive on LVM and put the stuff back. Now comes the problem. I use LABELS in fstab and would like to continue that. I can't figure out how to get the LABEL set for the LVM file system tho.

Re: [gentoo-user] sdhc card on eeepc701 running gentoo
Hello, I would guess the internal reader don't work properly for such modern cards. Especially for the 701 there exist some reports about similar problems. You may try on another (external) sd-card-reader which is specified for class 10 cards. Steffen.

It's simple I'm sure but I'm missing it. You should be able to use e2label (or tune2fs -L as I do) on the /dev/data/data1 device to set the filesystem label. That's the logical volume that the operating system needs to mount. # tune2fs -L mylabel /dev/data/data1 should do what you need.

Originally the data was on the 750Gb drive. I set the 250Gb up on LVM then moved things over from the 750Gb. I then added the 750Gb to the VG and resized the file system. So, in theory the data is on the 250Gb drive. Let's say I want to remove the 250Gb drive. I would use pvmove to do that right? When I ran pvmove /dev/sdb, which is the 250Gb drive, then it would remove all the data from that drive so that it could be removed. Am I close? I'm not planning to do that but just wanting to get a better understanding of this LVM thing. Dale :-) :-) -- I am only responsible for what I said ...
