I suggest that you run it on the text console after "dmesg -n 8", so
that all kernel messages are seen.

I'm using rt61pci with wireless-testing, and I don't see any freezes.

You can use "git bisect skip" to skip those revisions.

You can specify the paths in "git bisect start" so that only changes to
the interesting places (like drivers/net wireless, net/mac80211 and
net/wireless) are considered when calculating the next commit.  This
will probably help you avoid the bad place.

Also, please try the current wireless-testing.  The problem may be fixed
there.

Perhaps there was not enough material for others to comment on, and
nobody was experiencing anything similar.

If I had such problem, I would try to bisect it, but I cannot reproduce
it.
