The rest of the system is lenny, testing or sid? I suspect that it is lenny. In particular, module-init-tools from lenny is very slow, the one from testing is much faster. > > The parallel booting of script kind of works now.

In my 701 the main bottleneck is the CPU, not the harddisk, and looking at your bootchart figure I suspect that it also happens to you. > major issues: > the udev process takes an awful lot of time it just stays for more then > 7 seconds in the "Waiting for /dev to be fully populated" state probably > caused by udevadm settle.

Try udev and module-init-tools from testing/sid (both have speed enhancements since lenny). . > > sometimes my asus eeepc 901 just won't turn off at the last stages of > halt.

But nevertheless it is another issue, so you could post it as another mail, search the web or report it to the BTS.
