« on: January 09, 2012, 08:27:10 pm »

Bonjour!

Running it on an HP ProBook 4510s. So far so good, but can't tell any performance difference yet. I have to do some real testing. Also, I had read about the Intel IOMMU boot problems so I compiled the kernel with the following options at first:

CONFIG_INTEL_IOMMU=y
# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set

Will try with it activated by DEFAULT next.

Bonjour,

I didn't encounter that issue as the sharp mebuis laptop is driven by AMD xp-1500 cpu.

With the default kernel that came with VL7.0, everything works fine. However i wanted to try out 3.2 on reading this thread so downloaded kernel-src-3.2-i686-1vl70.txz, kernel-modules-3.2-i686-1vl70.txz, and kernel-3.2-i686-1vl70.txz and installed them using installpkg in that order. I then booted using the new kernel when i observed the internet not working. I also tried with vasm to configure dhcp, it didn't give any error but also didn't start the net.

With the new kernel running, did you run command "depmod -aq", then reboot?

Strangely it's working now  ???, not sure what happened earlier.

On a slightly different topic, i feel the machine to be little slow at times, i happened to choose jfs instead of ext4, could that be the cause?

Thanks for your help.

I did a JFS installation on a new SATA SSD hard drive a while back. I was thoroughly disappointed with the speeds. They seemed about on par with my ancient ATA/133 20GB consumer drive. I don't know if this was directly related to JFS choice or not, but JFS certainly did not give me the benefits that I was expecting it to.

I think JFS would work well in a specific environment. As a fairly normal desktop user though, I did not present it that environment.

An update: Works OK here with CONFIG_INTEL_IOMMU_DEFAULT_ON set. I am currently on kernel 3.2.4, downloading the 3.2.5 patch today, which is where the ASPM power regression issue is supposed to be finally fixed.
