Comment 0 for bug 100110

Every time I boot Ubuntu on my notebook, the boot procedure is delayed by 18 seconds. After selecting the kernel in the GRUB menu, the screen shows "Starting up", and then for 18 seconds absolutely nothing happens: no CPU activity, no disk activity, just waiting. After the delay, the boot procedure continues without errors or warnings.
When I reported this behavior to the ubuntuusers.de forum, it was confirmed by another user who uses the the same notebook model.

This seems to be a Linux Kernel problem because I have no delay booting Vista which is also installed on this notebook.

I'm using Kubuntu 7.04 on a FSJ AMILO Xi 1554 notebook (Core 2 Duo T7200, 2 GB RAM, 17", ATI Mobility Radeon X1900). The behavior was always the same for all kernels I've tested: Generic 32-bit kernels from 2.6.20-9 to 2.6.20-13.

bootchart tells me that before the delay "init", "khelper" und "kthread" are started in short succession, then the 18 seconds delay, and the "kseriod", "pdflush", "kswapd0", "aio/0" and "aio/1" are started.

The boot log gives me the impression that this is an ACPI problem:
