Known Problems, Unsolved
We've run into a handful of machines that reboot when you try to load anything down from the netboot menu, such as memtest. On the first of these machines we encountered, we tried downloading an ubuntu iso, and the md5sum was correct, there was no corruption in the file download that we could find.
List of machines with this problem:
- R61, BIOS version 1.1, Update to version 2.29 made no difference
Models
Thinkpad 600
- isa sound issues
modprobe cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=5 synthirq=-1 synthio=-1
Thinkpad 600e
- isa sound issues
modprobe cs4232 io=0x530 dma=1 dma2=0 irq=5
Thinnkpad T20/T21
- fan issues
YAY FIXED!
- SIMPLE
append:
acpi=force
to the grub boot options.
then:
echo 0x2f 0x07 > /proc/acpi/ibm/ecdump
typing that command and redirecting that output to the embedded control dump (ecdump) file will turn that fan on at it's maximum speed.
- Notes
this simple script found here:http://www.thinkwiki.org/wiki/ACPI_fan_control_script and take care of any unnecessary end-user interaction with the fan control. other useful information can be found their as well, about controlling the fan.

Thinkpad T30
RAM slot failure, it's a solder failure, usually starts in the second slot and worsens from there. http://www.thinkwiki.org/wiki/Problem_with_failing_memory_slot As-is these machines.
Thinkpad R60
In the frame buffer environment (pre-GUI) the top portion of the screen has a stripe of garbled (red) characters. This fix worked for this chipset:
$ lspci -k | grep -A1 VGA 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400 Kernel modules: radeon $ sudo gedit /etc/default/grup
Edit the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to read GRUB_CMDLINE_LINUX_DEFAULT="radeon.modeset=0 quiet splash"
.
Run
$ sudo update-grub
Reboot. Is fixed, no?
Thinkpad X61
- Issue
- Wireless device recognized, not working
- Details
- First thought was that the integrated Bluetooth device was having some kind of hardware conflict with the wireless card. Running
rfkill list
showed the wireless card subject to a hardware block, which usually stems from a wireless switch. However, flipping the wireless switch (physical switch immediately below the center of the palm rest, SoftKey = Fn+F2) would bring the bluetooth up and then down, but leave the wireless as it was. Turns out, the solution was a BIOS option. - Solution
- Enter BIOS (F1 on POST)
- Go to Config -> Network
- Set the Wireless LAN Radio Frequency option to On
And you're golden. Sheesh.
Thinkpad R61
- Issue
- Systems with BIOS passwords do not netboot correctly: System reboots when an option is selected
- Solution
- Install a hard drive, network boot should behave normally. Working hypothesis is the locked BIOS passes incorrect system information about a drive being present, and clobbers the netboot.
