after upgrade to 10.04 "unknown controller version you may experience problems"

[klossner]

I also am trying to run Ubuntu on a Latitude E6510. I just yesterday found a patch that lets me run the KMS Intel video driver:
http://bugs.freedesktop.org/show_bug.cgi?id=28070
Suspend/resume still doesn't work: the rest of the system resumes but the screen remains blank. That's being tracked here:
http://bugs.freedesktop.org/show_bug.cgi?id=28739

(I know, this is not on topic for this thread. I tried to send it as a private message but ubuntuforums.org says I can't do that until I have 75 posts.)

Klossner, could you please give us more details? Which packages have you installed/upgraded? Which kernel options are you using? Are you using "i915.modeset=0" as a kernel option? Thanks a lot in advance.

[klossner]

I'm running standard 10.04, with the exception of the kernel, which I built by taking the upstream 2.6.34 kernel and applying that patch. I'm running with no kernel command-line options which means I'm using the default i915.modeset=1. I get full graphics support, including compiz effects.

Now I'm chasing several other kernel problems on my E6510, but I don't want to take this thread off topic. You can email me directly by building an email address of the form my-first-name at-sign my-last-name dot org.

Hey everyone,

I am also having the same boot lag problem.

When I boot up, the system lags a good ~15 seconds.

I've added several performance tweaks found here:
http://linux.aldeby.org/speed-up-you...inux-boot.html

Also here are the logs, pretty much the same as some others:
dmesg:

Any insight into this, diagnosis suggestions or other help would be greatly appreciated.

Attached is my last bootchart image.

Thank you and God bless,

Any ideas or assistance would be greatly appreciated.

Found this:
https://bugs.launchpad.net/ubuntu/+s...9?comments=all

And this:
https://answers.launchpad.net/ubuntu/+question/2535

The 2nd looks promising however there is a broken link.

Any help would be appreciated.

I wonder if the Ubuntu team would mind including this driver in an update or the next revision to resolve this issue from now on?

Thank you and God bless,
Johnthan

OK, went ahead and did the update, and for me it didn't work.

Here is what I have thus far:

#!/bin/sh
# Fix the mmc "unknown controller" issue in Ubuntu with O2Micro MMC Readers
# See: http://www.denraf.be/content/o2micro-cardreader-dell-acer
# See: http://linux.derkeiler.com/Mailing-Lists/Kernel/2006-11/msg08170.html

# Install libhal-dev for PCSCLITE
sudo apt-get -y install libhal-dev

# Get PCSCLITE from http://pcsclite.alioth.debian.org/
wget https://alioth.debian.org/frs/download.php/3298/pcsc-lite-1.6.1.tar.bz2

# Install pcsclite
tar jxvf pcsc-lite-1.6.1.tar.bz2
cd pcsc-lite-1.6.1
sudo ./configure
sudo make
sudo make install
cd ..

# Get the source code to convert, Check out: http://linux.derkeiler.com/Mailing-Lists/Kernel/2006-11/msg08170.html
wget http://pieleric.free.fr/o2scr/O2Micro_PCMCIA_SCR_203_Linux_Kernel26_OpenSource.tar.gz

# Unpack
tar zxvf O2Micro_PCMCIA_SCR_203_Linux_Kernel26_OpenSource.tar.gz
cd OZSCR_2.0.3_Kern_2.6

# Perform the install
sudo ./configure-release
sudo modprobe ozsrclx

Also, I've emailed O2Micro. They informed that they will not develop a Linux driver since the Linux community already has.

So we have to figure this out on our own.

Any help would be greatly appreciated.

God bless,
Johnathan
