Hi, I managed 2 days ago to compile and set up the latest 2.0.35 with rtl patch- RELEASE9H. However, this morning, when trying to boot the kernel, it stops after the message: Calibrating delay loop. Corrupted stack page Lots of "memorymap (?) adresses showing up, then it says: And finally: idle task may not sleep (repeated 5 times). And the computer completely locks up. Any ideas why ? I've had many head-aches with rtlinux, but the strange thing this time is that I *did* manage to boot the kernel on wednesday, but today (and I have no idea *what* can cause this), the kernel locks up. (I have to turn *off* the computer with the power switch). I am currently running redhat 5.1. Any help will be greatly appreciated -christophe --- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] ---- For more information on Real-Time Linux see: http://www.rtlinux.org/~rtlinux/
