Comment 8 for bug 96693

nope, u mis-understood me, the issue is also with me :-

 sudo hdparm -I /dev/sdb |grep dma

 DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5

   as you can see I am stuck at udma2 & cannot go upto udma5 hence even my reads are not good.

uname -a
Linux ubuntu 2.6.20-14-generic #2 SMP Mon Apr 2 20:37:49 UTC 2007 i686 GNU/Linux

 sudo hdparm -c 1 /dev/sdb
/dev/sdb:
 setting 32-bit IO_support flag to 1
 HDIO_SET_32BIT failed: Invalid argument
 IO_support = 0 (default 16-bit)

 sudo hdparm -tT /dev/sdb

/dev/sdb:
 Timing cached reads: 448 MB in 2.00 seconds = 223.66 MB/sec
 Timing buffered disk reads: 54 MB in 3.02 seconds = 17.90 MB/sec

Hopefully this output is helpful.

hexion, what I meant was if there is another kernel which fixes the issue it would be well worth the download
