| |
Hi,
For my own enjoyment I've been playing around with 2.2.1 under _extremely_ low memory conditions. (LILO: linux single mem=1718k) The only kernel configuration options selected are ELF , E2FS, and basic IDE support. I do not even have /proc selected.
One thing that I have noticed is that even after swapon -a has completed successfully and there is plenty of swap I get "Bus Errors" when executing simple commands like vi. Shouldn't these just be slow and not error out like that? I post this only in hopes that it might help someone track down a bug occuring in a more common configuration than 1.7M ;-). I don't seem to see these in a 2M configuration.

P.S. I'm happy to report that 2.2 seems to be the most efficient Linux kernel yet. It seems to scale down further that 2.0 and is even slightly smaller than the "TinyLinux 0.5" kernel which is 1.2.11 based. From 386SX/16-2MB with no HD and 1 floppy to a 64 parallel processor 64bit Sparc with Gigabytes of RAM, The scalability is certainly there. Congratulations.
