Feisty don't boot at IBM Thinkpad R40

well, I looked into the issue again:

From 2.6.17 to 2.6.20 the naming schema for ide-devices changed. And I didn't adjusted the device names in grub/menu.lst. Specially 'root=/dev/hdFOO' was the problem. Because of this the initrd:/scripts/local scipt loops for 180 (!) seconds around '/lib/udev/vol_id ${ROOT}'. This script only writes an info message about a following 180s timeout operation to the splash-screen via '/sbin/usplash_write' - and I have the splash screen disabled ... - thus nothing is printed to the screen.

After replacing the wrong ide-device names in grub-config, the machine boots fine with 2.6.20.

To debug these kind of problems, adding 'debug=y' to the kernel command line helps a lot, btw (initramfs scripts issue a lot of extra output to the console).

To sum it up:
- perhaps 180s timeout for waiting if the root devices shows up is perhaps too long. Which harddisk controllers need 180s to initialize their attached harddisks?
- /sbin/usplash_write should write to the console, if the splash screen is disabled (i.e. 'splash' is not included in the kernel command line)

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!
