Just to report that this appears to be the smoothest running kernel for me
also. All machines are pre-patch-2.0.31-2 + perfect-patches. My FireWall
box has not shown a 'free pages' report in it's 2 days of up time (not
unusual though). I tried a make -j on my 16meg 486DX/2 66 and watched it
use up all of my 32meg swap and spit out some:
kernel: hdb: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
kernel: hdb: read_intr: error=0x10 {SectorIdNotFound }, CHS=649/6/17, sector=51600
which I expect are caused from my failing drive that I should have fixed
before now. It then failed to complete this make because virtual memory
was exausted. So I set it to make -j10 which it seemed happy to run with a
load of 12 or so and I could still use/do other things.
On an 8meg 486 on a UMSDOS partition, not really stressed, it certainly
runs fine.
On a 4meg 386sx25 UMSDOS, I could not see any difference though between
this and the original 'Werner?' patches, but again, this is too
subjective.
