With all the SCO fun going on I have people asking me what functionality
we would loose if we rolled from 2.4.21 kernel to the last known stable
2.2 kernel.
Yes, weathering the lawsuit mess and all is a good plan but I'm still
being asked for this information. Does anyone have a link listing what
kind of functionality would be lost, performance impact (p3 and athalon
machines), etc?

No highmem support,
No journaled filesystems.
No netfilter. Fewer networking features. Period. (ethernet bridging, etc)
Slower SMP
I don't know if it's psycological, but whenever I booted 2.2 on my desktop,
it felt slower.
This was a while ago though.

You could start with Joe Pranevich's "Wonderful World of
Linux 2.4" at
http://linuxtoday.com/news_story.php3?ltsn=1999-10-03-001-05-NW-LF
There have been a number of improvements and features added
since but any 2.2 -> 2.4 features summary should indicate
much of what you would loose in a 2.4 -> 2.2 transition.

it is easier to turn off SMP.
BTW: what will happen if there is some SMP code from IBM in the kernel which
is owned by SCO? Isnt it a matter of days to remove that code? Does anybody
have to pay for past usage of the code?

The core 2.2 SMP code is stuff I wrote. Caldera (aka SCO) even provided
me the hardware and asked me to do it. The later table parser code is
from Intel.

Too bad you don't have anything they gave you or which they took back
from you that could be used against them.

Did you open up the boxes? Perhaps there was some license note attached to the
internals (`by using this machine, you declare to give up your first born
etc... ')?

But would just turning off SMP shut up the lawyers? They're saying it'd
take a full roll back to 2.2.
Having Gartner say not to take the suit seriously isn't helping calm
down the lawyers, etc even if there is no proof.
http://www.nwfusion.com/news/2003/0523gartntous2.html
Right now there's just a bunch of rumors and stories of people like M$
paying license fees which argumentably provides a precedent. (tactics
of M$ asside, M$ isn't the topic here)

The only reason I'm still using 2.2 is that my binary of realserver won't
run on 2.4.x.
