Hello,
I have a Supermicro PIIIDME with dual Pentium 800E Processors inside, two
ide Maxtor DiamonMax Plus 40.9 Gb (Primary master and secondary
master) and one Quantum Atlas 10K on a Adaptec 2960 160Mb/s (64 bits).
My root and boot are on hda, and the rest is on sda (with /tmp and
/var/log on hda too). The fs I use is reiser-fs, except for /boot which is
ext2 (as said necessary in the manual).
I run SUSE 6.4 (kernel 2.2.14 with SMP). My two processors are listed, and
I can make SMP on them. But...
The problem is that if I set the dma on the ide hard disks using
hdparm -d1 /dev/hda
and then copy a large size pack of files (say 700Mb) between the sda and
the hda, then I have "Segmentation faults" during the copy, or even
worse the "cp" command is listed in the processes but nothing works (no
disk activity, and the cp command takes 0% cpu) and I cannot kill the
process. And then sometimes the system halts (I have to reset the computer
manually).
If I remove the udma setting, everything works fine.
The problem is that without udma, my Maxtor drives are pretty slow.
What can I do ? Buy a bunch of SCSI ?
Thanks,
Yann Le Du
