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.
