Subject[BUG] 2.6.11: Random SCSI/USB errors when reading from USB memory stick
Date
From
When trying a "dd if=/dev/sda of=/dev/null" (where /dev/sda is an USB
memory stick), this works fine for some seconds (and actually transfers
data at around 700-1000 KB/s), but ends up with some I/O errors sooner
or later, which cause the device to go offline (the stick must be
replugged to make it accessible again). Sometimes, this causes kernel
bugchecks and hung "dd" processes (which cannot be terminated even with
kill -9), see second example.

Two examples (syslog message outputs) are appended below, in both cases,
short USB reads seem to initiate the trouble.

I also tried running a kernel latency test program simultaneously: When
the errors occur, the latency goes up from less than 1 millisec to about
15 millisec (very bad for embedded control systems...).

The error occurred on an intel Pentium 3 (500 MHz) embedded system with
440BX chipset and 192 MB RAM. USB is handled by the 440BX (intel 82371
PIIX4). The UHCI driver shares interrupt 7 with an intel 82559ER 100
Mbit ethernet controller (which is driven by the e100 driver and active:
As there is no local keyboard, I access the system by ssh).

The system "disk" is a 128 MB CF card directly connected to the 440BX
primary IDE port and running in PIO mode 2 at about 2 MB/sec peak (but
it is idle most of the time). There is a SM712 VGA chip running in text
mode, a 1000 HZ std PC timer, and no other "interesting" device (nothing
else on the PCI bus or causing any interrupts).

The error was reproduced with statically linked (no modules)
vanilla-2.6.11, 2.6.11-gentoo-r3, and
realtime-preempt-2.6.12-rc1-V0.7.41-11 kernels, all built with gcc
3.4.3.

I tried with two different sticks (an old 64 MB USB 1.x and a 1 GB USB
2.x), both show the same problem on all USB interfaces on the target.
The same dd command works fine on both sticks on my office PC.

I suspect some kind of timing / bus / interrupt trouble, either due to
the interrupt shared between uhci and e100, or due to the extremely slow
PIO transfers (which seem to block interrupts).

What can I do to solve or further analyze the problem?

Thanks!
