Hi, I have written a kernel module that does frequent memory allocs, reallocs and deallocs. The code randomly crashes at one of the two memory allocation parts - either in krealloc() or in kmem_cache_alloc_notrace (called by kmalloc()). However, when I analyzed both the crash points instructions using gdb, they both turned out to be at the same location in slab_alloc(). I have tried to debug by carefully inspecting the trace dump and my code. However, I am not able identify the problem. All that I get in the trace dump is "general protection fault: 0000 [#1] SMP". There is one more of this message and then the machine just hangs and I have to reboot it (I think any 3 successive general protection faults requires a reboot). Is there some way that I can debug this problem? -ctmzb _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
