Yeah, I've seen this. For me, this is the direct result of the ServerWorks chipset on the box not properly doing DMA, and in fact causes corruption on the bus when DMA is enabled for the IDE controller. Usually you see this when doing large extracts or deletes (like the openoffice of mozilla/firefox ports). You need to fsck, hopefully before you even read this (you'll see lots of softupdate problems being fixed). You'll also notice that your daily automatic reports sent to root will mention problems with traversing files or directories. For reference this bad boy: atapci0: <ServerWorks ROSB4 UDMA33 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xfc90-0xfc9f at device 15.1 on pci0 atapci0@pci0:15:1: class=0x01018a card=0x00000000 chip=0x02111166 rev=0x00 hdr=0x00 vendor = 'ServerWorks (Was: Reliance Computer Corp)' device = 'OSB4 PCI EIDE Controller' class = mass storage subclass = ATA The only solution is to run with dma off (see atacontrol, or shut it off in BIOS). -- othermark atkin901 at nospam dot yahoo dot com (!wired)?(coffee++):(wired);
