You should upgrade. REALLY. > 1. What is the reason for multiple enteries in TLB > due to module insertion? A machine check exception will be generated if during a TLB lookup (for example during instruction fetch or loading/storing the data for a load rsp. store instruction) multiple entries match. > 2. Should the TLB operations be performed with interrupts disabled? Yes; the kernel does so. Ralf PS: Ditch that 2.6.10 antique! It belongs into a vitrine in the MIPSonian Institude, not a life a computer system :-) PPS: Have you considered upgrading your kernel?
