Are you getting alot > of network throughput on these boxes? None at all. But from what you say, and Steven's recommendation of the Redhat 2.4.18 kernel, that sounds like the kernel we want to be on. Our problem with the kernel, thought I doubt it's precisely familiar to anyone who hasn't been through this specific pain, is that our motherboar has an Intel ICH6 IDE controller on, and a Highpoint 373 (I think). And I believe that only 2.4.19-ac1 had the right combination of drivers and RAID support which allows both controllers to work as a RAID1 array using DMA. I think 2.4.18 wouldn't use DMA on the Intel controller and earlier versions had other problems... argh, all a bit of a muddle. Anyhow I'll download this host kernel: ftp://ftp.mirror.ac.uk/sites/ftp.redhat.com/pub/redhat/linux/8.0/en/os/i386/SRPMS/kernel-2.4.18-14.src.rpm and see whether it looks promising for tomorrow. I think I should in fact veer *away* from trying to find a UML patch which is "better behaved" because that's just trying to mask the problem. -- Matthew Bloch Bytemark Computer Consulting Limited http://www.bytemark.co.uk/ tel. +44 (0) 8707 455026 |
