In the hope to collect some useful information, I installed the linux-crashdump package. When the problem occurs, the system is now restarted (instead of freezing). After rebooting, there is a ~30MB file called linux-image-2.6.32-23-generic.0.crash in /var/crash. The apport tool tells me that a kernel crash has occurred and asks whether I want to send a report. If I try to do this, it sends ~30MB somewhere (presumably the crash file), but then tells me that a server error occurred and that the data could not be sent successfully.

I'd really like to help, but I do not have the time to study how kexec, crashdump, etc. work in detail. Is there an easy way to get at least some information out of these tools? Is there a "Debugging kernel crashes in Ubuntu"-Howto somewhere?
