The crash, over netconsole, same run as dmesg

reported upstream: http://marc.info/?l=linux-netdev&m=123612024109003&w=2 Could this be related as well? http://thread.gmane.org/gmane.linux.bluez.kernel/1549 The bluetooth patches have been rebased in kernel 0.207, can you try this again? 2.6.29-0.207.rc7.fc11 seems to work ok (I've not gotten the headset to work, but there's no crash anymore). Rawhide is on .197, I pulled .207 from Koji to test. Closing. I've seen some lockups after finishing with Bluetooth on kernel-2.6.29-3.fc10.x86_64, have the patches made it into this kernel? |
Created attachment 333774 [details] The dmesg pre-captured before crash Description of problem: After pairing the earpiece, kernel oopses (GPF). Version-Release number of selected component (if applicable): 2.6.29-0.148.rc6.fc11.x86_64 How reproducible: 100% (in the given configuration) Steps to Reproduce: 1. Connect USB adapter 2. hcitool scan 3. hcitool cc MAC 4. Wait - it's not synchronous. Takes some idle time to happen. 5. Oops Actual results: Crash Expected results: No crash at least Additional info: Terminal trace: [root@simbelmyne zaitcev]# hcitool dev Devices: hci0 00:18:E7:36:30:3A [root@simbelmyne zaitcev]# hcitool dev Devices: hci0 00:18:E7:36:30:3A [root@simbelmyne zaitcev]# hcitool scan Scanning ... 00:1A:0E:43:6D:5E Motorola H350 [root@simbelmyne zaitcev]# hcitool cc 00:1A:0E:43:6D:5E [root@simbelmyne zaitcev]# hcitool cc 00:1A:0E:43:6D:5E [root@simbelmyne zaitcev]# <--------------- crash at this point after some idle time I've done hcitool cc twice here, but actually it happens with just one too.
