This is the same as bug 214622. A couple other people have reported this bug too... People were also getting bug 216001 which has a similar trace. One of those reporters was using cifs, but i'm not sure about the other. |
Description of problem: The problem occurs in exactly the same circumstances on two otherwise very stable different hardware platforms. When performing multiple mount/umount of network shares of type 'cifs' the initilization of SELinux causes the kernel to crash. The problem is reproducable on these two machines with regularity. However, various amounts of log are available depending on how fast the kernel killed itself. Version-Release number of selected component (if applicable): System A: 2.6.18-1.2849.fc6 System B: 2.6.18-1.2798.fc6 How reproducible: Consistantly Steps to Reproduce: Repeatedly mount/umount a network share of type 'cifs' using a mount command similar to this: mount -t cifs //192.168.x.x/sharename /mnt/sharename -o\ credentials=credentials.txt,dir_mode=0777,file_mode=0777 ...along with a simple 'umount /mnt/sharename' Actual results: Eventual kernel crash. Expected results: Stable system operations. Additional info: Please feel free to contact me for further information. I am willing to assist with the debug process.
