Unfortunately it appears the problem still exists, or maybe it's another
one with the same visible effects.
I don't use the windows share very often, and with large files it's even
less often, so I just found out today.
Trying to copy a ~180Mb file from the same machine (still using the same
kernel) to the same share, I had the same problem. Eventually, after
30min and lot's of freezes the file was copied but corrupted.
Here
One thing is different, this time I got messages in the system logs,
they repeat for the whole time the file was copying.
Also, after copying the file I had this strange (-6) ReqActive count, is
it expected? Now (about 10 min later) it shows 0;
