Hi stek79, Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/karmic . If the issue remains, please run the following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 285595 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message.

Hi, I had the same problem with my Thinkpad T61 and a hard disk Ultrabay adapter using Jaunty. Linux reported a 40-wire cable and used UDMA/33. However, adding libata.force=80c to the kernel boot options solved the problem and the Ultrabay adapter is now connected with UDMA/100.

I confirm this bug exists on 8.10 (mythbuntu)
BIOS is set to UDMA 100 and shows it at startup, but hdparm reports
udma2 and dmesg the 40-wire cable - NOT!
I tried this solutions that worked for a guy:
Modified /etc/modules:
Code:
fuse
lp
#custom start
amd74xx
mousedev
psmouse
via82cxxx
piix
ide-core
#ide-generic
ide-disk
ide-cd
#custom end
Added to /etc/hdparm.conf:
Code:
/dev/sda {
dma = on
io32_support = 1
write_cache = on
}
but it did nothing for me - any suggestions?
BTW: System is old but proven capable of running at udma5...

[Bug 285595] Re: Intrepid kernel UDMA/33 (slow disk transfer rate)
I have the same problem with Ubuntu 8.10 (latest updates). I have a CDROM writer/DVD reader attached with a 80 way cable. It is supposed to be able o do UDMA/100 but is being limited to UDMA/33 by an erroneous claim that the cable is 40 way. I realise that in the case of a CDROM drive the loss of performance is pretty minimal but it's a bug just the same. DMESG is enclosed.

Ubuntu intrepid i386

Hello
full confirm on that, my thinkpad t23 has no cable for detection. The
disk connector is soldered to the mainboard. The controller can do
udma100, has done this for 7.xx versions and does it when booting such
old live cd. Kernel with hdX runs well, with sdX they are slow.
Board and controller can do:
[5.562716] scsi0 : ata_piix
[5.563078] scsi1 : ata_piix
[5.565677] ata1: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0x1860 irq 14
[5.565685] ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0x1868 irq 15
But when detecting the disk (transcend ssd) it fails.
[5.728373] ata1.00: ATA-8: TS8GSSD25-S, FW0625, max UDMA/100
[5.728383] ata1.00: 15604848 sectors, multi 0: LBA
[5.728408] ata1.00: limited to UDMA/33 due to 40-wire cable
[5.736757] ata1.00: configured for UDMA/33
So the ssd runs slowdowned at not as fast as possible.

PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2 udma3 udma4 udma5
What to do? Use a very old kernel from 7.xx with lots of problems to fix
this? I have no bios limitations in the machine that can be adjusted.
