preempt with selinux NULL pointer dereference

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After using it for a good few hours, I launched a shell script in a terminal and got the traces below.
I hope this helps (if not, please let me know how to make it helpful or I'll just stop testing -rc kernels and save myself some time)
