Of course, I'm super user. Nothing is printed in dmesg.
I'm on linux-2.6.16 and motherboard is Fujitsu Siemens D1561 with an
ICH5. I also have a SATA hd in the computer and this only happens when
the SATA hd is there. If I remove the SATA HD, then I can enable DMA
for the PATA hd.
Disabled combined mode in BIOS.
If only that was possible on my fscking T43. *sigh*
The other way around is to make libata handle the PATA devices. I'm not
sure if the support for that on combined mode is in mainline or if you
need Alan's libata PATA patch for that?
