The speed increase of recompiling for i586 or whatever wouldn't be all that dramatic, and besides, you changed your kernel, not your make. I have a Celeron 700 running an i386 make 3.79.1, and see no such problems. You should try booting your old 2.2 kernel and see if the problem goes away. If it does, then the kernel is the only difference. You might want to look at your swap usage. How much memory does this machine have? Also, what differences are there between the 2.2 and 2.4 kernel configurations? It could be that your 2.4 kernel is not set up for efficient usage of your hard disk. hdparm can tell you whether DMA and multi-sector I/O are being used; check that under both kernels. Craig
