Date: Mon, 4 Aug 2008 21:44:41 +0100 From: Alan Cox <alan@...rguk.ukuu.org.uk> To: David Stuart <dstuart@...ers.com> Cc: linux-kernel@...r.kernel.org Subject: Re: Problems with disk + network on 2.6.25.11-60.fc8 Ok so the pdc202xx_old hardware flakes out when you have very high network load (I'd guess in fact very high bus traffic). The actual log is the disk I/O timing out, then the drive being busy (probably due to the timeout and a DMA transfer getting stuck). We reset it and carry on. Libata happens to log this a lot more visibly than old kernels which is useful but does mean people sometimes don't notice. The rest then fits - the freeze I'd expect as we block I/O while trying to get the drive back. Doubt the Nvidia module is involved as I'd then expect problems under high graphical load but you can certainly test that. I don't suppose you've got a spare PCI network card you could try instead to see if it is the network card bits ?
