ThinkpadT42

DragonFly on an IBM Thinkpad T42

Installed System

I ran a recent kernel and world build from HEAD:

jupiter!matthias:~ % uname -a
DragonFly jupiter 1.11.0-DEVELOPMENT DragonFly 1.11.0-DEVELOPMENT #1: Sat Jan 26 20:05:28 CET 2008     root@jupiter:/usr/src/sys/compile/JUPITER  i386

Wired Network

Installed Intel E1000 works with em(4).

Wireless Network

The built-in Atheros card works fine with ath(4). I use WPA with wpa_supplicant, also working flawlessly.

Power Management

ACPI Suspend to ram (S3) works. You can suspend the machine with acpiconf -s 3. Sadly em(4) doesn't survive a suspend/resume cycle. The card will not reattach cause of an EEPROM checksum error. To avoid problems with USB and the internal ath(4) card, I unload the two modules in /etc/rc.suspend and reload the modules in /etc/rc.resume. Furthermore if you suspend with X running, you have to restart the moused(8).

Gathering information about the battery also works:

jupiter!matthias:~ % acpiconf -i 0

Speed stepping

est(4) works out-of-the-box, I used pkgsrc/estd to control the frequency.

jupiter!matthias:~ % sysctl machdep.est
machdep.est.frequency.target: 1700
machdep.est.frequency.current: 1700
machdep.est.frequency.available: 1700 1400 1200 1000 800 600

Sound

Works with snd_ich(4).

PCMCIA

Tested with an external ath(4) card, works.

Graphic driver

The built-in ATI Radeon works with the default X.org ati driver. The display resolution is 1440x1050. Never tested DRM or DRI or any kind of graphics acceleration.
