Over the last month or so I made a lot of changes in the usb-storage driver to fix up its DMA accesses. Your system ought to be a good test case. If you still get DMA errors, please send a detailed debugging log.

Another thing to try is turning on verbose scsi logging (IIRC, type: echo scsi log all /proc/scsi/scsi) before trying your mount command. (Don't do this if your system log is on a scsi disk, because it will create logging messages for the logging entries themselves!) Also, I'm not familiar with the OHCI driver, so I can't help you too much even when you do get some good debugging info.

[linux-usb-devel] Problem with AIPTEK usb-pendrive
Hi, I have a problem with the usb-storage driver on a PowerPC hardware. My Linux Kernel is 2.4.21-rc7 from the PowerPC devel tree. This is what happens: First I load the usb-ohci driver (PCI hostcontroller is a Philips ISP1561BM). This OHCI host controllers has two USB1.1 hosts, one USB2.0 host. I only use the OHCI controller. After loading the ohci module, I modprobe the usb-storage driver. It detects my AIPTEK 32MB USB pendrive. Then I mount /dev/sda1 under /mnt, but this mount never returns. I cannot interrupt the mount call, but the system keeps on running. Furtheron I noticed that the AIPTEK parts can be mounted when the usb-storage debug option is turned on in the kernel. I that this changed the timing behavior a lot. Any idea? I hove no such problems with a USB-CompactFlash card reader attached to this hardware. My hardware plattform is a custom specific PowerPC design with an IBM405GPr PowerPC CPU. Here ist my syslog.

Have you tried mounting it read-only? Also, can you tell where the mount
process is hung? Try Alt-SysRq-T (and make sure you have enabled the
Magic SysRq key in your kernel).
Since my system is an embedded platform without keyboard, I can only post a strace
output
from the mount command. As you can see, the call blocks in the open systemcall on the
/dev/sda1 device.
When I interrupt the strace/mount with CTRL-C the open() call is interrupted
unfinished.
Without strace the mount call cannot be interrupted by CTRL-C.

As you can see, the call blocks in the open systemcall on the /dev/sda1 device. When I interrupt the strace/mount with CTRL-C the open() call is interrupted unfinished. Without strace the mount call cannot be interrupted by CTRL-C. Can you try using your device on a regular PC? Can you try using Linux 2.5.70 to see if that helps? Can you enable OHCI_VERBOSE_DEBUG near the start of the ohci driver source file in drivers/usb/host?
