Regarding the oops that I reported for PPC architecture that reported "Unable to
handle kernel paging request for data at address 0x000004c", I have now repeated
it on x86_64 architecture, where the objdump tool is better. The error occurs in
the line in __netif_schedule() that says
if (!test_and_set_bit(__QDISC_STATE_SCHED, &q->state))
Debug printouts have shown that q is not NULL, and it appears to be in the
correct address range. I think q->state is zero; however, q->state cannot be
written.
Additional testing shows this problem to be another side effect of commit
3a25a8c ("mac80211: add improved HW queue control") for a device with only a
single HW queue.
Any suggestions for additional debugging printouts will be greatly appreciated.
Thanks,
Larry
