--- Begin Message ---Package: bluez Version: 4.66-3 Severity: normal rfcomm crashes with kernel bug (see dmesg trace below). Needs reboot to clear situation. Post crash the rfcomm process hangs and cannot be killed. I tried kill <pid>, kill -9 <pid>. No more rfcomm connections can be made. Further "rfcomm connect X" create hung processes as well. rfcomm is called from a bash script (fetch-s0), stripped down: while [ 1 ]; do rfcomm connect 0 & sleep 5 if [ -c "/dev/rfcomm0" ]; then stty -F /dev/rfcomm0 115200 raw echo command > /dev/rfcomm0 read -t 1 response < /dev/rfcomm0 fi rfcomm release 0 sleep 100 done The loop executes successfully for a few times, then it crashes. ------------- lsusb ------------- Bus 001 Device 007: ID 0a5c:2039 Broadcom Corp.

--- Begin Message ---Hi, your bug has been filed against the "linux-2.6" source package and was filed for a kernel older than the recently released Debian 7.0 / Wheezy with a severity less than important. We don't have the ressources to reproduce the complete backlog of all older kernel bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy or a more recent kernel from testing or unstable, please reopen the bug by sending a mail to [email protected] with the following three commands included in the mail: reopen BUGNUMBER reassign BUGNUMBER src:linux thanks Cheers, Moritz
