[solved]hda: dma_intr: error=0x84...Difference between knx 3

[JoDaY]

Bonjour !

I had a knoppix 3.1 installed since february, all was ok !...

Filesystem was ext3

2 weeks ago I've installed v3.2 (06/06) with reiserFs:

since:the system alert me in telling that my hda dma is not enabled
and I got lot of
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }

at boot and during the use ( in terminal and in dmesg )

I believed it was caused by filesystem changing... So I tryed an install in ext3...
The messages appears so...

I tried the Kde version of Knoppix 3.1: no messages...

I couldn't find some relative change in the changelog.

I'd like to know if my hard drive is going to fail or if its a parameters problem...?

nb:i've made a test from Western digital and It seems to be ok

Thanks a lot!

I used to get that all the time when my drive was jumpered to 32gb instead of the full 40gb that it is, when I upgraded the motherboard and it supported the larger drive it went away do you have a similar situation?

hi !

well i think i've the latest bios for my Abit kt7 i could have, but i'll check if a new release is available...

The hard disk is 40 Go and it is recognised at this.

nb: I've a 120Go on ide2 (hdc) and not have message about this pbm...

It's strange for me that knoppix v3.1 doesn't report this pbm

Tks for your interest

Bonjour !

I think I've finded a begining of soluce about my problem...

I've found an interressent article ( http://www.linuxgazette.com/issue76/tag/10.html )

My /dev/hda seems to have problem with dma:

the difference between Knoppix 3.1 & Knoppix 3.2 is that the first has not enabled dma on my drive no problem is so reported

I'll turn off my dma in order to wait testing if a cable is not responsible of this trouble

Check if dma is enable on /dev/hda:

hdparm -d /dev/hda

Disable dma:

hdparm -d0 /dev/hda

Enable dma:

hdparm -d1 /dev/hda
