Ok,
 for everybody who thought "stoned beaver" wasn't an appropriate name for
a kernel (yeah, I'm sure IBM really minds my naming scheme, and is deathly
afraid it will scare away customers), I'm happy to tell you that the
beaver just went into detox, and I'm taking the Thanksgiving weekend off.

I give you "Beaver in Detox", aka linux-2.6.0-test11. This is mainly
brought on by the fact that the old aic7xxx driver was broken in -test10,
and Ingo found this really evil test program that showed an error case in
do_fork() that we had never handled right. Well, duh!

While at it, this also pulls in some firewire fixes and a few potential
skbuff leakage points.

Please don't even bother sending me patches, because I'll be stuffing my
face away from email over the next few days. And after that it will be up
to Andrew to say how to go on from here.

Mmmm. Turkey.


		Linus

Does that mean you'll be ready to flame proposed 2.7 changes
soon, even if integrating them will be a few months into the
future ? ;)

I've found an odd problem that's in at least 2.6.0-test11.  I've
reproduced this twice now with an Epson 1240 USB scanner
(0x04b8/0x010b).  What happens is if I run xsane from gimp, acquire a
preview, start to scan and then cancel, the scanner becomes
unresponsive.  If I try and quit xsane, it gets stuck.  Unplugging /
replugging and then trying to kill xsane locked the machine up hard.

Here's ver_linux, dmesg and the versions of gimp/xsane I'm running (I've
used the scanner during this boot, without trying to lock it up):

Can't you use xsane without the scanner kernel driver?  I thought the
latest versions used libusb/usbfs to talk directly to the hardware.
Because of this, the USB scanner driver is marked to be removed from the
kernel sometime in the near future.

After a bit of mucking around (and possibly finding a bug with debian's
libusb/xsane/hotplug interaction, nothing seems to run
/etc/hotplug/usb/libusbscanner and thus only root can scan, anyone whose
got this working please let me know), the problem does not exist if I
only use  libusb xsane.

Did it happen in older versions of Linux? I haven't heard of any
similar bug reports until now.

This may be a bug in the plustek backend which supports that scanner.
The cancel handling is pretty complicated with some scanners.

That sometimes happens with other scanners, too. E.g. some don't like
to get a "stop scan" command in certain situations. They just hang
after that command and further commands run into the USB timeout.

Well, obviously that should't happen. But it's really hard to debug
without any oops. There was a bug in the scanner driver that occured
when a device was open, then unplugged and then an application wrote
to it. But it's fixed since some time.

Does the freeze also happen if no other USB devices are attached? I guess
working without a keyboard is not that easy but it may be worth a test.

Otherwise I don't have any ideas.

Bye,
  Henning

I hadn't tried.

I can xhost things to another machine rather easily.  But Greg KH talked
me into switching to libusb for the scanner, and everything works
perfectly now.  Do you still want me to give it a go?  Thanks.

If it doesn't happen with libusb it's really most probably a bug in
the scanner driver so you don't need to test. However it's pretty much
uncommon that nobody else sees this problem. I'll mention it on my
website so it's not forgotten.

Thanks,
  Henning
