FW: PS/2 mouse lagging
If you don't find your brand in the kernel configuration, download the appropriate kernel patches for DMA acceleration written by Andre Hedrick, from http://www.kernel.org/pub/linux/kernel/people/hedrick/. Luckily, your kernel version 2.4.17 has a patch available. -Ramesh | | blacktop:/home/mandingo# for i in a b; do hdparm -d 1 | It won't let me.

PS/2 mouse lagging
Any time there is any hard drive activity, my mouse will freeze up until the hard drive stops being accessed. This has only happened since I've downgraded to woody (reformatted). I do not have a slow computer. I'm running a Athlon 1200, 1 GB of RAM, and UDMA 100 HDDs. I'm also using kernel 2.4.17. Any ideas? --Patrick

Do I have to enable something in the kernel? Um. Generic PCI bus master DMA support should be Y, and to save you issuing the hdparm you can set Use PCI DMA by default when available. CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_IDEDMA_PCI_AUTO=y Kind Regards Crispin Wellington

Do I have to enable something in the kernel? What ATA speed does your mobo support ? What ATA speed is your HDD ? If your mobo runs at a lower speed than your disk you may need to go to your disk manufacturers website and grab a utility that you can use to force your disk to run at the lower speed. I know in theory all these ATA standards are supposed to be backwards compatible, but my own experiences tell me otherwise. Simon Hepburn.
