Has anybody seen this before? The system is freshly installed RedHat 9.0, no SKAS; the UML used is standard 2.4.20 kernel with 2.4.20-3um patch. I have also seen this panic with 2.4.17 UML.

Deleting the line (void) CHOOSE_MODE(signal(SIGCHLD, SIG_IGN), (void *) 0); from arch/um/kernel/process.c before compiling the uml kernel seems to get tt mode working. Michael Young |
