Then run as root:
cat /sys/kernel/debug/tracing/trace_pipe > /tmp/output1
The command will continue to run.
Use the adapter as you normally do to reproduce the bug. When that has
happened, please check (in another terminal) that
cat /sys/kernel/debug/tracing/tracing_on
contains "0".
Then kill the first cat trace_pipe command and attach the resulting
file /tmp/output1 to the bug.
If you can repeat this 2-3 times in different output files it'll be even
better!
Ah, indeed. Only the 1GB controllers l1c, l1d, l1d_2 support jumbos. Sorry I
didn't pay attention to that.

/* Fast Ethernet controller doesn't support jumbo packet */
That's good news in fact because it means that it's always possible to
allocate buffers so that they don't straddle a page boundary for this
hardware.
The "theory" remains speculative however. Could you please run one more test? download. opensuse. org/repositorie s/home: /benjamin_ poirier: /branches: /home:/ david_chang: /bnc812116_ atl1c/openSUSE_ 12.3/ 8649C33B
