I don't know what you would define as crippled, but I'm on a 4 day old Dell Inspiron 8600 with a 2GHz processor, 768MB Ram. Interestingly, and this may have nothing to do with it, but even though I have a 780MB swap partition and fstab seems to have picked it up, it doesn't seem to be 'enabled'. I mention this because I've heard that the kernel likes to have 'some' swap space. fdisk /dev/hda shows: Disk /dev/hda: 60.0 GB, 60011642880 bytes 255 heads, 63 sectors/track, 7296 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 6 48163+ de Dell Utility /dev/hda2 7 372 2939895 7 HPFS/NTFS /dev/hda3 373 715 2755147+ db CP/M / CTOS / ... /dev/hda4 716 7296 52861882+ 5 Extended /dev/hda5 * 716 725 80293+ 83 Linux /dev/hda6 726 1745 8193118+ 83 Linux /dev/hda7 1746 1843 787153+ 82 Linux swap / Solaris /dev/hda8 1844 5158 26627706 83 Linux less /etc/fstab shows: # This file is edited by fstab-sync - see 'man fstab-sync' for details LABEL=/ / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 LABEL=/home /home ext3 defaults 1 2 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 LABEL=SWAP-hda7 swap swap defaults 0 0 less /proc/meminfo shows MemTotal: 774344 kB MemFree: 11500 kB Buffers: 26664 kB Cached: 255784 kB SwapCached: 0 kB Active: 381484 kB Inactive: 166756 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 774344 kB LowFree: 11500 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB Mapped: 324336 kB Slab: 201824 kB CommitLimit: 387172 kB Committed_AS: 998888 kB PageTables: 4052 kB VmallocTotal: 245752 kB VmallocUsed: 3332 kB VmallocChunk: 242204 kB HugePages_Total: 0 HugePages_Free: 0 Hugepagesize: 4096 kB
