Did you enable kernel debugging options?
The crash is much harder to reproduce without them.
We have these set:
        [*] Kernel debugging
        (17)  Kernel log buffer size (16 => 64KB, 17 => 128KB)
	[*]   Detect Soft Lockups
	[ ]   Collect scheduler statistics
	[*]   Debug slab memory allocations
	[*]     Memory leak debugging
	[*]   Mutex debugging, deadlock detection
	[*]   Spinlock debugging
	[*]   Sleep-inside-spinlock checking
	[*]   kobject debugging
	[*]   Compile the kernel with debug info
	[ ] Debug Filesystem
