Hi,
I'm trying to copy a large file (200Mb or bigger) from an ext3
filesystem to a windows share mounted using CIFS and the cp process
hangs, sometimes for a long time (several minutes).
Calling ps, I can see that it's blocking on blk_congestion_wait.

Trying to edit a file on the same ext3 filesystem using vi blocks on the
same function. However, during that that same time that vi and cp were
blocked, I was able to do a "find /usr/share/doc" and it completed
normally, in a few seconds.

Eventually the copy succeeds but it takes a long time (20 minutes to
copy 200Mb) and the computer is unusable during most of that time.

This is copying from my laptop (IDE disk), the network card is a RTL8139
using 8139cp drivers.

Is someone seeing a similiar problem? What extra info is needed to debug
it?

Thanks

Mmm, anyone with a similar problem? What should I do, make a profile
like explained in Documentation/basic_profiling.txt or is the above
information about the function where the processes are "stuck" enough?
One thing I forgot to mention, during the several minutes the processes
are stuck on that function there is no disk activity, so it's not the
processes being starved. In fact, there is no other activity on the
machine apart from the copy.

A sysrq-t back trace of that process would be interesting to see.

OK, apparently now the cp never finishes and nothing gets written to
disk, so i could not get the full output from sysrq-t.
I wrote the call stack from the process, it that enough?
The call stack from the cp process:
__make_request
schedule_timeout
process_timeout
io_schedule_timeout
blk_congestion_wait
autoremove_wake_function
autoremove_wake_function
get_dirty_limits
balance_dirty_pages
generic_file_aio_write_nolock
__copy_to_user_ll
file_read_actor
__generic_file_aio_read
file_read_actor
generic_file_write_nolock
do_sync_read
do_IRQ
common_interrupt
generic_file_write
cifs_write_wrapper
do_sync_read
vfs_write
sys_write
syscall_call

Also the call from a vi process that was called after the cp reached
that state and was also blocked
schedule_timeout
ext3_mark_inode_dirty
process_timeout
io_schedule_timeout
blk_congestion_wait
autoremove_wake_function
get_dirty_limits
balance_dirty_pages
generic_file_aio_write_nolock
buffered_rmqueue
__alloc_pages
generic_file_aio_write
ext2_file_write
do_sync_write
do_lookup
path_release
sys_access
vfs_write
sys_write
syscall_call

If more detail is needed I can try to capture it but syslog not writing
to disk I don't know how to capture the sysrq-t output

Thanks

Hi, is the above information enough to try and find the problem or is
there a way that I can capture the full sysrq-t output?

Hi,
I retested this using 2.6.7 and still have the same problem.
This is copying a 197Mb from an my laptop's IDE hardisk to a cifs
mounted share that's on a Win2000 Server. The laptop has 512Mb.
Here's an lspci:

I used netconsole to catch the sysrq-t output, it's attached. Note that
besides the cp process there is a vi process that also froze.
