Too many questions in this comment :-) (In reply to comment #20 from Thomas Renninger)
There were ioremap and pci transparent bridge related patches which may fix (or cause this): http://bugzilla.kernel.org/show_bug.cgi?id=11054 http://bugzilla.kernel.org/show_bug.cgi?id=9961
Related patch: git commit id: 12c22d6ef299ccf0955e5756eb57d90d7577ac68
Revert "PCI: remove transparent bridge sizing"
This reverts commit 8fa5913d54f3b1e09948e6a0db34da887e05ff1f,...
This could be the reason why the older (2.6.22) Ubuntu kernel works (guessing only). At least the first bug (11054) is related to (a rather old) ThinkPad and its docking station.
I need to dive deeper into this. If you know how to compile a kernel, I'd try latest git with and without above patch.
I will try this and let you know the result.
Can you boot into text mode and take pictures of where it hangs, possibly also scroll up a bit and picture everything important?
What do you mean by text mode ? (init 3?) I am not sure if anything will get printed at all. I don't have a camera to take a snap shot of it. I will try my best.
I can reproduce this. It happens atleast twice a month Ohoh, any idea how to always reproduce this (maybe if you have added a specific device or AC to the dock station it always happens or similar)?
I tried Ubuntu 7.10 which has 2.6.22-14 kernel and it did not hang. Hmm, how can you say for sure if it only happens every month?
With 11.0, I have not observed this often. Because, I was working more from office where there is constant power supply etc. But, with 11.1 , I manually disconnected power supply (to check this bug) and it is hanging whenever i remove the power supply. I tried with around 5-6 t60p laptops here and everyone of them hung (with 11.0 live dvd and 11.1 installation). So, I guess it should be fairly easy to reproduce. Please note that I am using a full-featured docking station with pci interface etc. (not a simple port replicator)
Can you also paste or attach /proc/iomem and acpidump.
I shall do that. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
