Debugging Kernels that do not completely die (no Panic)
I am looking for a way to debug a kernel lockup condition. I am trying the new kernel 3.7.0 rc2. It is working for about 40 minutes and then it is freezing. The keyboard is frozen, the display is frozen and the sound card is continually playing the last second or so. What I would like to do is get a good trace of where this is happening. I have checked the /var/log/messages on the next boot, and the dmesg and do not see anything of note. Any ideas? I am a newbie with kernel debugging, although I have successfully built the kernel from source and set a few options in it.
