Bug Description

Binary package hint: linux-source-2.6.20

Suspending works only once on this NC6400 notebook.

By default the first time doesn't work either, given that the i8042 driver must be compiled as a module, not in kernel, otherwise the keyboard won't work on resume (without echo -n reconnect > /sys/bus/serio/devices/serio0/drvctl) and psmouse must be unloaded before suspending and reloaded on resume.

But, on the second time calling suspend I get this oops message about some NULL pointer:

On my Samsung X20 XVM 1730 suspend to ram works also only once. After the second suspend no login is possible. On the console are no commands possible, always the same error message: scsi 0:0:0:0: rejecting I/O to dead device.
Why are my partitions now called sdxy? In edgy (and before) they were called hdxy...
Might that be the error?

Christopher, is this the same error you reported in bug 109762?

For me this bug no longer occurs in 2.6.22 from ubuntu gutsy. I'm now explicitly unbinding/binding the i8042 driver on suspend and using newer x.org intel video drivers.

The correct wiki page referenced by Tim Gardner on 2007-02-26 is probably https://wiki.ubuntu.com/DebuggingKernelSuspend

I had the same problems on X20 (on ubuntu Dapper it worked). With "suspend2" it works now again. For instructions, see:

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.
