I saw earlier you had a thread to get textdumps to >work. Did you ever have regular crashdumps working? No. I have another deadlock panic when savecore is running. That panic dumps core, then on reboot when savecore is running I get another deadlock panic, and so on. However, I do get about 8-10gb vmcore* files before the panic happens. Presumably these are truncated somehow. Do you think these incomplete vmcores can still be useful? If you send some instructions on what to try, I'll give it a go, or I can post a vmcore somewhere.
