Hallo benlogo,
ich habe ähnliche Crashes hinter mir und erfolgreich Debian Sarge mit PCMCIA installiert bekommen. Da Ubuntu und Debian eng verwandt sind, solltest Du unbedingt probieren, den Adressbereich 0x800 bis 0x8FF für PCMCIA zu sperren:
Ich zitiere aus dem Debian Handbuch:
Some laptop models produced by Dell are known to crash when PCMCIA device detection tries to access some hardware addresses. Other laptops may display similar problems. If you experience such a problem and you don't need PCMCIA support during the installation, you can disable PCMCIA using the
hw-detect/start_pcmcia=false
boot parameter. You can then configure PCMCIA after the installation is completed and exclude the resource range causing the problems.
Alternatively, you can boot the installer in expert mode. You will then be asked to enter the resource range options your hardware needs. For example, if you have one of the Dell laptops mentioned above, you should enter
exclude port 0x800-0x8ff
here. There is also a list of some common resource range options in the System resource settings section of the PCMCIA HOWTO. Note that you have to omit the commas, if any, when you enter this value in the installer.
