Hi all, I know that the 2.* version has SMP support, but when I build and work on the kernel, the system gets stuck with the inter process interrupt error message "Stuck on TLB IPI wait (CPU#0)". Also an error message like "Unable to handle kernel NULL pointer dereference at virtual address 00000000" appears in the boot-up message. My system has two Pentium Pro processors and I am working with RTL2.0 on 2.2.13 kernel. So I would like to know if there are any people out there who have succesfully compiled and worked with RTL2.* on a multi-processor machine. If so is there any thing I should take care of when building the kernel? In the recent Dr.Dobb's Journal it is mentioned that the RTL is not suitable for SMP. Is it true? if so what are the limitations of the RTLinux? Hope to hear your comments on this, Surya. -- [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/
