Software Environment:
Linux version 2.6.7 (root@e275d) (gcc version 3.3.3 20040217 (Gentoo Linux
3.3.3, propolice-3.3-7))

Problem Description:
Writing on USB2 Mass Storage device through SCSI layer freezes a short time
after writing. Top shows heavily increased load but no process on the top seems
to take that CPU time. This happened with an USB2 plugged hard disk. The kernel
 has no patches. Also, there are no third party drivers. Pure 2.6.7 Vanilla.
Reading from the same USB2 hard disk causes no problems. I was trying to write
on a VFAT device. Writing on the same disk on the other machine on 2.4.26 with
USB1 didn't cause any problems.

Kernel log says:

...
many thousand lines of reject.




Steps to reproduce:
Plug a hard disk with USB2. Create a filesystem with mkfs.vfat, start writing to
a file, say dd if=/dev/zero of=/mnt/usb2/foobar. Soon after write buffers are
started to be flushed on the disk the writing stops and machine load increases
by 2-3. Writing small amounts of data does not cause problems even if written on
the disk.

Comment 2 Georgios E. Kylafas 2004-07-19 00:08:29 UTC

I had similar problems ("rejecting I/O to offline device") with my USB hard 
drive on x86. 
 
They were solved by _not_ compiling "SCSI generic" support (CONFIG_CHR_DEV_SG) 
either into the kernel or as a module (following the discussion in bug 1827). 
 
Does it work for you too?

Georgios, I will try that later and report here. Thanks in advance.

There have been lots of changes in that subsystem. I will assume 
for now it's fixed. If not please reopen and assign to USB maintainers
instead.

The side-effect that load starts to increase doesn't happen anymore with linux
kernel 2.6.12. But USB2 doesn't still work perfectly. Now I'm able to write
approximately 60 to 120 GiB before I get problems:

  scsi4 (0:0): rejecting I/O to dead device
  FAT: FAT read failed (blocknr 44749)
  scsi4 (0:0): rejecting I/O to dead device
  ...

I will file another bug report when I've made some more tests. Now USB2 is only
annoying, but at least it works a little because I can write relatively large
amounts of data before failure.
