Hi.
I've tested IDE HDD performance on 2.5.47-ac6.
Using old pentium-classic PC-9800 box, it has no DMA mode.

 1. "hdparm -t /dev/hda3" results (PIO mode)
  2.5.47-ac6 with Task file IO:    2.86MB/s
  2.5.47-ac6 without Task file IO: 2.90MB/s
  2.4.19 without Task file IO:     2.93MB/s

 2. Heavy usage test
  "cp -pr /usr/src /tmp/foo" (in same HDD)
  about 92000files/total size 2.3GB
  I had always "lost interrupt" message and FS corruption
   by this test at 2.5.20 days.
  2.5.47-ac6 works fine. (takes about 30 minutes.)

Thanks,
Osamu Tomita
