*** Bug 217915 has been marked as a duplicate of this bug. *** Can the reporter test the latest kernel (2.6.20-1.2952 or later) and report? Many bugs have been fixed in CIFS. This appears to be a dupe of bug 224359, please reopen if this is still occurring in recent kernels. *** This bug has been marked as a duplicate of 224359 *** |
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.
