 Posted: Tue Jan 15, 2008 4:13 pm Post subject: Dell Latitude d820 - no DMA, disk very slow with >2.6.22 |
 |
|
Hi,
After I upgraded from <2.6.20 to >2.6.23 my disc which was sda before was renamed to hda. I think this is due libata activation. My problem is that actually i'm not able to activate DMA and disc transfer is very SLOW.
| Code: |
# hdparm -Tt /dev/hda6
/dev/hda6:
Timing cached reads: 4982 MB in 2.00 seconds = 2495.54 MB/sec
Timing buffered disk reads: 12 MB in 3.46 seconds = 3.46 MB/sec
|
I'm using 2.6.23 actually and I get this output from dmesg:

I also upgraded bios from A05 to A07 with no new results. The system is almost unusable with some I/O. Any idea?! |

Hi
Had similar problems.
Fixed thanx to this guy: http://guido-flohr.net/dell/latitude-d820/#Harddisk
I assume that this works for 2.6.23 as well but haven't tested yet.
Let me know if it works for you 
FTR hdparm reports for my setup:
| Code: |
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 6754 MB in 1.99 seconds = 3387.84 MB/sec
Timing buffered disk reads: 102 MB in 3.03 seconds = 33.70 MB/sec

I had that problem 6 to 10 months ago (I think with a 2.6.18 kernel) and the disabling of generic_ide definitely did the trick.

Yes, this solution worked for me with 2.6.23 and 2.6.24 and 2.6.22. I know this because I have all 3 kernels installed at the moment.
