Thanks for the tip; this is my first experience with 2.6.13, and I know that it's not 'perfect' as yet. What was really suggesting to me that it might be a kernel scheduling issue (aside from the fact that I know that kernel scheduling issues are coming rapidly to a boil in several areas), is that nothing has particularly changed on my system, inosfar as I have run several high-priority processes concurrently under X with previous kernels, but have not noticed this issue under, say, 2.6.12. If this is a kenel issue, is 2.6.13-r5 likely to be any better than -r4? I can't go to 2.6.14 since the ATI drivers won't compile under it, afaik (that was the situation a couple of days ago, and I haven't checked to see if the current 'unofficial' (?) patch has made it into any of the trees yet). What could I do to minimize the problem (are any of the schedulers set by default so "icky" that I should disable them, for example)? > > BTW, are you using any kernel based network filesystems (NFS, Samba, > ncpfs), FUSE, or PPP?

But he may have screwed up something in the network, for all I know; I simply haven't had the time to check, though the issue is moving slowly yet steadily up the chain of priority). But, similar to my suspicion of gamin, it did occur to me that Samba could be trying to connect behind the scenes, and repeatedly failing. Anyway, I'm not going to be able to compile 2.6.13-r5 for a day or two (well, I can compile it, but I won't be able to boot to it for a day or two, so I'm not compiling it yet), so any other tips for special treatment of the kernel or anything else are still more than welcome.
