[I am not subscribed to this list, so please reply to my own address] I have a HP ZV6100 . I have installed debian serge, then updated to etch. but either with 2.6.8 or 2.6.15, k7 or 486 i am unable to activate dma and in turn the computer freeze almost completely during disk access (expecailly if i download large files from a fast lan server). The hardware is fine since if i use a 2.6.12 from ububntu the dma is correctly activated and i can also activcate/deactivate it with hdparm. Any hint ? possible kernel personalization to get it to woik ?
This can happen when your IDE controller's module is not loaded early
enough during boot. I think you need the module "atiixp", but you have
to check yourself with "lspci" (look for "IDE interface: ..."). You can
then either compile a custom kernel with the driver included statically,
or you can add the module to /etc/mkinitrd/modules and use
"dpkg-reconfigure linux-image-2.6.15-xxx" to rebuild your initrd with
the module. Sometimes it can also be necessary to explicitly include the
module "ide_generic" in /etc/mkinitrd/modules, but then it should
probably be listed after (below) the specific module of the IDE controller.
