Hi there again. Kernel 2.4.17 keeps falling over *very* frequently. As per my previous posting, I have had yet another Oops which makes that two crashes in three days. I never had these problems with 2.2 kernels. What is wrong with 2.4.17? Will it help if I upgrade to one of the 2.4.18-pre kernels? I would tend to think that hardware is _not_ the problem here, as the only thing I have changed is the kernel. This same server was rock solid when running kernel 2.2 only last week. I have gone back to using RedHat's prebuilt 2.4.7 for now. I'm sorry I can't test any further, but the machine is a production server, and can't be shut down. What is going on? I have attatched the ksymoops output. The problem (again, as before) is in prune_dcache. Please cc: replies. Thanks for your help! -Patrick.
