Bug#668142: linux-image-2.6.32-5-openvz-686: serial_unthrottle+0x44/0x5a [usbserial]()

Thanks, good to know. Am I correct in guessing that 3.2.y from wheezy, sid, or squeeze-backports is not affected? The only packages from outside squeeze that should be needed for this test except for the kernel image itself are linux-base and initramfs-tools. If that's works, please do test the patch[1] Ben suggested, like so: 0. preparation apt-get build-dep linux-2.6; # as root apt-get install devscripts; # as root apt-get source linux-2.6/squeeze cd linux-2.6-version 1. disable debuginfo sed -i -e '/686_image-dbg/, /^$/ d' \ debian/config/i386/openvz/defines 2. patch and build # optionally with -j num for parallel build bash debian/bin/test-patches -f 686 -s openvz /path/to/patch; 3. install and test dpkg -i ../name of package; # as root reboot Sincerely, Jonathan [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=10;bug=668142 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Hi Jonathan, problem still persists. It happens, if Asterisk is restarted. This Asterisk has chan_dongle-1.1.r10 installed, which provides connectivity to a mobile provider.

Unthrottling the TTY during close ends up enabling interrupts on a device not on the active list, which will never have the interrupts cleared. Doctor, it hurts when I do this.

We struck the issue, and the patch below (against 2.6.32) fixes it. Should I supply a patch against 3.0.0rc? I think that would be sensible. I don't actually see how you hit it as the IRQ ought to be masked by then but it's certainly wrong for n_tty to be calling into check_unthrottle at that point.
