My configuration is:
NCR53C810 SCSI controler in PCI slot 3 HPT366 a NCR have IRQ
11
/dev/sda1 OLD Seagate SCSI HD
/dev/sdb1 HP 1GB HD
/dev/sdc1 Seagate Barracuda 2Gb
/dev/hde1 my new IBM DPTA 13.6 GB UDMA66.
I run this test 10 times.
mount /dev/sdc1 /mnt -t ext2
cd /usr
cp -a . /mnt
I switch to another console and run.
cd /usr/src/linux
make dep; make clean; make -j3 bzImage
All works fine. Where is the problem ?
