Description Fix 2007-03-01 10:50:45 UTC
Description of problem:
Process of copying a large file (~700Mb) to flash drive deadly hangs after 
first few megabytes, with no messages neither in /var/log/messages nor dmesg.
ps shows that usb-storage status is 'D' (uninterruptible sleep).
With smaller files all is ok. Very similar issue was discussed at Ubuntu 
bugzilla (bug#17881):
+bug/17881 . Besides my FC6 box, the same issue have present on my FC4 box.

My flash drive is 1Gb Kingston.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. mount flash drive
2. start copying to it a large file using cp or mc.
3. wait :-)
Actual results:
The speed of copying quickly decreases until it deads at all.

Expected results:
The file was copied successfully

Additional info:
Bug # 17881 (Ubuntu):

Comment 1 Pete Zaitcev 2007-03-01 21:07:05 UTC
What does happen if you use ub? Please boot with libusual.bias="ub" in grub
and use /dev/uba1 instead of /dev/sdb1 (or whatever is an appropriate
device in this case).

Dave/Chuck: I'm not taking this for now because it seems like the reoccurence
of the old writeout throttling issue (notice how ancient Ubuntu's kernel is).
Might be something for riel to look into, if it can be reproduced.

Can we change settings in /proc/sys/vm to keep this from happening?

Moving this one to FC6, since it seems to actually be active.
