usb disk hangs under load (fc3 with various 2.6 kernels)

[dmitri]

I have an external USB hard drive (Maxtor OneTouch), which hangs whenever I try to write lots of data to it. After it 'hangs', cpu foes to !00%, I cannot access or umount the drive until reboot. Happens under all 2.6.9 and 2.6.10 kernels (FC3 & kernel.org) that I've tried. Happens on vfat, ext2, ext3, and reiserfs. The 'noapic' boot option seems to only make things worse (i.e., the drive hangs faster). The USB drive is plugged into a PCI USB 2.0 card.

This problem does not occur if I plug the drive into a USB 1.1 slot on the motherboard. Also, the problem does not happen under windows (i.e., the hardware is OK).

Any help would be greatly appreciated (this is driving me nuts...)

Steps to reproduce:
boot, mount drive, copy lots of data to it (~5-10Gb), drive hangs

In /var/log/messages I get a thousand of:
Jan 20 19:14:40 *** kernel: SCSI error : <2 0 0 0> return code = 0x70000

No problems with my drive
I am currently running 2.6.10-1.741_FC3 also using a Maxtor External 250Gb model one touch
and a PCI usb 2.0 card only having a single processor.

try searching this site and looking for messages from Alan Stern
http://www.spinics.net/lists/usb/

and as a wild guess try relocating your PCI card to another slot??

[lirakis]

I have similar problems, and i have tried putting my pci usb 2.0 controller into 2 different fedora machines both have trouble. My drive will some times just go really slow when i do an ls and then it will freeze up the console. Also I can not chown the drive at all and its only writeable by root. I am using a lacie 250gig model that has a western digital drive inside. I suspect it has some thing to do with my pci card.. just a generic compusa brand usb 2.0 controller.. any help would be VERY appreciated.

I have the same problem - except my USB2 is onboard, not a PCI add-in.

I can read a small amount of data, but then the whole thing locks up - needing a reboot.

It works fine in Windows, so I assume the device is OK.

It doesn't seem to make any difference which port I use.

[jarifed]

Try this (can't guarantee it works)

enter in a terminal as root
cat /sys/module/usbcore/parameters/old_scheme_first
It should either return Y or N

If N then you can change old_scheme_first to Y as follows

echo Y > /sys/module/usbcore/parameters/old_scheme_first
use cat /sys/module/usbcore/parameters/old_scheme_first and it should return a Y

I have set capital letters as that's what is showing on my FC3 kernel 2.6.10-1.741_FC3

Additionally you can check this also
cat /sys/module/usbcore/parameters/use_both_schemes
in my case it returns N

[lirakis]

I got it!!! The problem was a GHETTO usb controlloer made by 'ALi' on my pci usb 2.0 card. I got an Adaptec with an NEC chip on it and it worksgreat.

[dmitri]

Yeah, I'm starting to believe that my ALi USB PCI card is the root of all this mess. I was hoping to avoid buying new hardware, but I guess I'm running out of options...

BTW, I also tried setting 'max_sectors' to 32 and 64, and tried the 'old_scheme_first' thing, and it didn't help.

[dciarnie]

I have an ALi USB 2.0 card which worked just fine with kernel-2.6.10-1.766 but when I update to kernel-2.6.10-1.770, I started to get SCSI errors like those listed in this thread's initial post. One of the changes between 766 and 770 is to change old_scheme_first from N to Y and I'm thinking that this might be the problem. How can I restore the setting to N at boot?

Thanks,
Dan.

dciarnie
this should do it

echo N > /sys/module/usbcore/parameters/old_scheme_first

Jarifed

[dciarnie]

Thanks, Jarifed. I did that and was able to transfer a large file without any SCSI errors. The only problem is that when the system is rebooted, old_scheme_first gets reset to Y. I would like this to be automatically set at boot time. I believe that there is a way to set module options at boot time but I haven't been able to figure out how to do it.

Alternative 1
In /etc/grub.conf, for the kernel you'd like to use, add usbcore.old_scheme_first=1 to the kernel line.Example:

...
title Fedora Core (2.6.10-1.770_FC3)
        root (hd0,6)
        kernel /boot/vmlinuz-2.6.10-1.770_FC3 ro root=LABEL=/ rhgb quiet usbcore.old_scheme_first=1
        initrd /boot/initrd-2.6.10-1.770_FC3.img
...

Alternative 2
Add what jarfield suggested above to the end of /etc/rc.local:

echo N > /sys/module/usbcore/parameters/old_scheme_first

[dciarnie]

Thanks, Jowa. Adding usbcore.old_scheme_first=0 to grub.conf did the trick.
