Hello, I have trouble with my system to use UDMA, works 100% with dma
disable....
I have mandrake 7.1, ABIT BP6 (dual celeron 366) with htp366 controller
(not-overclock) and some large disks.
Well the systems hangs BAD when I enable UDMA transfer, no logs off the
error just total freeze.
After hours (and lots of coffee) searching for answer, I found this on the
reiser FAQ:
- Can I use 32GB+ IDE Hard Drives with reiserfs ?
-Yes, but you need a patch to work it properly.
-Although, you have to turn DMA off.
So is this true, I have tried to rmod reiserfs and umount disks using reiser
but the problem still occurs, must I compile a new kernel without reiserfs
support???
Have others problem with the htp366 controller when its full (4 disk)???
The system worked with udma when I had 7.0, "only" two 27 gigs and no
reiserfs.
I have tried this without any success....:-(
- new kernel update 2.2.16 from mandrake
- kernel 2.4.0-test2 (with reiserfs)
- noapic to boot parameter
