For details, please visit the bug entries and follow the links given in
references.
As you can see, there is a Bugzilla entry for each of the listed regressions.
There also is a Bugzilla entry used for tracking the regressions from 2.6.30,
unresolved as well as resolved, at:
http://bugzilla.kernel.org/show_bug.cgi?id=13615
Please let me know if there are any Bugzilla entries that should be added to
the list in there.
Thanks,

Hm, I had no debugging enabled, but I think a silent hang in
pty_write()
tty_flip_buffer_push()
flush_to_ldisc()
can cause the receiving side
tty_read()
n_tty_read()
to wait forever for updates. I haven't looked closely. It seems to
be gone with your latest master in any case.

The folks on the wireless project have concluded that the problem I reported is down to a hardware
problem when power saving is switched on on for my Belkin cardbus wireless adapter, so now I simply
turn power-saving off when wlan0 comes up. I did, however, ask whether anyone was going to fix the
fact that once power-saving turns the LEDs off, they never come back on again, but I haven't had an
answer. Is that a regression? I guess the answer is no, because power saving in the rt61pci driver
is feature that is new to 2.6.31. Should it be fixed? I think the answer is yes, but being unable
to do it myself, I probably don't have a vote :-)
All I can do is report that I now know how to avoid my laptop freezing and leave the decision as to
whether it should stay on the regression list to you and the folks from the wireless project.
Thanks,
Chris

Well, IMO it is a regression, because it had worked before the power saving
feature was added.

Well, if you remind the developers about the issue from time to time, it may
help. ;-)

Can't recall this issue was ever reported, but that might just be me having overlooked some emails
or have completely forgotten all about it. But here is a test patch to see if this helps in the issue,
it is not really correct for upstream, but if it works I can see if there is a better solution.
Thanks,
Ivo

I've tried the patch without success. The card doesn't seem to wake up
again when I attempt network activity after PS has activated.
(Actually, There are two assumptions I should check out here. Firstly,
the LEDS going out is a sign that PS has activated and secondly, that
the card should "wake up" if I attempt network activity after PS has
activated).
