Arjan -- Thanks for your reply. Using schedule_timeout still causes the seg fault at sched.c line 327, prio_array_t *array is null and deferenced (array->nr_active--) . So it is more likely a bug with 2.6.0-test9 or uml, but I haven't heard from the uml camp yet. -Sean ----- Original Message ----- From: "Arjan van de Ven" <arjanv@redhat.com> To: "sean whalen" <swhalen@denature.org> Cc: <kernelnewbies@nl.linux.org> Sent: Wednesday, November 19, 2003 3:36 AM Subject: Re: interruptible_sleep_on_timeout error? -- Kernelnewbies: Help each other learn about the Linux kernel.
