I have two problems I was not able to solve even with Hedrick's
UDMA patch for 2.2.12. There are still appearing error messages
while:
>>booting of kernel with enabled DMA (on 2.0.38 or 2.2.12)
hda: dma_intr:status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr:error=0x84 { DriveStatusError BadCRC }
...
hda: DMA disabled
I rather turned off activating DMA when booting but to my suprise I am
still getting these messages ! I can see these messages anytime when
I try to turn on DMA via hdparm.
My computer:
PII Mendocino 333
Tekram iBX P6B40-A4X
128 MB DIMM 7ns
IDE:
hda: HDD IBM 10.5 GB 5400 ot.
hdc: CD-ROM Lite-On 40x (master)
hdd: CD-ROM Creative Infra 5400 (slave)
Creative SB Live!
Debian 2.1 is in logical drive of the extended partition.
At last I used hdparm -c 1 -u 1 -p 4 to increase 4 MB/s to 8 MB/s (hdparm -t)
and stayed sorry I cannot use DMA.
Do you think it is because of these combination of components ?
----------------------
The second problem - the bigger one - is mounting CD in slave CD-ROM.
If I try it I can see error - bad inode (asc = 0x64), bad superblock,
cannot mount filesystem. Master CD works good.
Slave does not support DMA and that is why I set PIO 4 for both of them
to prevent possible errors. But still does not work. When I try hdparm:
>>hdparm -u 1 -c 1 -p 4 /dev/hdd (on 2.2.12)
lost interrupt
hdd:cdrom_pc_intr: The drive appears confused (ireason = 0x 1)
...
... and still these messages on the console until restart
I tried kernel 2.0.38 too:
>>hdparm -u 1 -c 1 -X 12 /dev/hdd (on 2.0.38)
hdd: irq timeout: status=0x58
hdd: ATAPI reset complete
hdd: media changed
I even disconnected Lite-On CD and let Creative be the only one (master)
on the secondary IDE but those errors remained ! CD-ROM alone works in
DOS and Windows and both CDs work there too.
Have you ever met with this hardware or these problems ?
Thank you,
Ferda Prantl
