Hi,
first of all, I am not complaining, or calling things buggy. I know that what I am running is "work in progress" and that one gets what one deserves :-) 2.4.x has been stable for me and given me no severe problem besides the changed pcmcia/cardbus support somewhere in 2.4.4-acx
Just let me add my observation. The VM behaviour of 2.4.5 (started with some 2.4.4-ac kernel) is definitely less than an improvement for *my* setup. I am running a Thinkpad570 with 128 MB memory and about the same amount of swap (I know, against reccomendation).
Under the new VM behaviour, I easily get in a situation where the system feels very sluggish. At that point in time, about 70-80% of memory are Cache, the rest is Used and some small amount of free. Swap is usually less than half filled and paging activity is about zero (some sporadic page out). Typical case is a kernel build plus a Netscape session. No unusal behaviour showing up in "top" - just sluggish system response.
My gut feeling is that the Cache is pressing to hard against process memory. This may be great for some setups, but it is not good for others (like mine).
What would be great (maybe someone is already working on it) are some tuning measures to tweak the cacheing behaviour.
Just my 2 (Euro-)cents.
