ubuntu 8.10 (intrepid ibex) troubles with an old Acer Travelmate 630

I could not run the ubuntu live installcd and also the alternate hang sometimes. After a successful install X freezes. I tried to boot with various boot options. Only with acpi=off my system seams to working but with fan running and no battery info. An older knoppix was running, so i decided to install older ubuntu kernels and saw my system running with a gutsy kernel (2.6.22) but not with a hardy kernel (2.6.24).

What changed inside the kernel?

After searching a lot i found pci=nommconf.

It seams that something in the way pci is configured has changed.

script to rescue/backup a raid1 system and restore from a cd with initramfs

Searching for a rescue system that creates a bootable CD to restore my system i found mkcdrec. Because sometimes things (mkcdrec/debian/ubuntu) changes and i had to test and patch for new mkcdrec versions, so i droped it.

Then i started to make a live CD with debian-live and make my install script by myself. I also dropped it (long boottime and had too much to hack to let it work like i wanted).

Now i had the idea to build my own script that tar's my system and builds a bootable cd. I liked the idea of initramfs to extend it like i will and it boots much faster. The only drawback is that all things are hardcoded and have to be changed for every system i backup. But its only a single script: Read More...
