Everytime I boot with SMP kernel, the system hangs (stops responding) sometimes by giving a kernel panic, sometimes the display goes off. In all cases I cannot attempt rebooting using CTRL+ALT+DEL. I entered into BIOS and disabled MP1.4 as recommended by some sites dealing with SMP problem with ASUS motherboard. The system smoothly booted, but failed to start the ethernet (eth0) interface. I checked if the driver module is there in /lib/modules/2.4.7-10smp/ directory as it is in /lib/modules/2.4.9-13/ (non-SMP generic) directory. I made appropriate correction in /etc/lilo.conf also. Can anyone please suggest, where the problem is. One more amazing thing I notices. I was testing the performance by using a multi-threaded Java program to calculate PI using Monte-Carlo simulation. For 90,000,000 iterations using non-SMP generic kernel, it took 21 seconds, while for the same iteration using SMP kernel it took 32 seconds!! Please suggest me any solution. I am trying for the last several weeks. The configuration of my system is given below: Mainboard: ASUS CUV4X-D Processor: Two Intel PIII/1000MHz Coppermine Memory: 2 x 256 Mb I/O: Adaptec SCSI Controller AHA-2460 80MB/sec Disk: Seagate Cheetah, 10000 RPM Ethernet: RealTek 8029 (using ne2k-pci driver) Thanks in advance, Snehasis Sinha
