this today from realtek. Haven't had a chance to test it yet. I don't
quite understand the email message & don't have time to crash my laptop
today trying to fix this, maybe someone else can give it a go?

Ok this driver only seems to exist in the Ubuntu kernel in Lucid and
later, creating appropriate tasks.

1) I can confirm everything Matt has said so far on my machine. iwpriv -a is
definitely the cause of the problem
2) Obviously I cant copy paste so good from a non-X vt on a machine that has
had a kernel panic. I took a photo however (attached)

Matt, I wonder if you're not getting part of the strace output because
the kernel panic happens before the data gets sent over the wire? Can
you try running strace in a non-X vt (i.e. ctrl-alt-f1, then run
strace)?

Zach, sorry for the delay. so far no real help from realtek though they

Matt, What so far has been your conversation with realtek? Can you get
them to possibly bring the discussion into the open (perhaps even here)
so others can pick at their brains and maybe help come up with patches?

provide a
As far as I can tell, the module is open source. It's just not part of
the mainline kernel. I think we should push all open-source drivers
that aren't part of the mainline kernel to aim for inclusion. Even if
it doesn't get accepted, the kernel devs should at least provide some
direction for imp
When you say upstream, do you mean moving the module to open source &
kernel inclusion? i really doubt they have any interest. Though perhaps
if someone who actually knows something spoke with them, the Realtek
people would make some progress.

Is there any effort to get this code upstream? I strongly suspect the
code could use a thorough review by the kernel devs.

I am also affected by this. I am using stock open source ati driver.
Is there any other information I can provide or anything I can do to
help debug this? A quick google doesn't reveal any good sources for
other versions of the driver for this card.
Same problem with the newer driver (0017.0507.2010) on 2.6.32.
Corruption is now at 8145ffbd. fglrx 10.6 is in use.

Alex, any movement on this? e.g. is there a new upstream rtl8192se
driver? looks like lp:592745 might be a duplicate, so it's affecting
others as well. thanks, matt

As I said, this problem still occurs with 2.6.34 mainline kernel and
latest r8192se_pci from Realtek. I have a sneaking suspcicion that the
root cause is that the code is crap.

Hi Alex,
If you could also please test the latest upstream kernel available that would
be great. It will allow additional upstream developers to examine the issue.
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the
upstream kernel, please remove the 'needs-upstrea
The r8192se_pci driver seems a bit flaky in general. I would appreciate
it if someone familiar with wireless driver code would take a quick look
at the r8192se_pci code and tell me if it is, in fact, a disgusting
collection of kludges, as I am beginning to suspect that it is.

This bug also occurs when I use the mainline 2.6.34 kernel with the
latest r8192se_pci driver from Realtek's website. Therefore, I believe
the r8192se_pci module is ultimately responsible.
