If xace hardware reports a bad version number, the error handling code
in ace_setup() calls put_disk(), followed by queue cleanup. However, since
the disk data structure has the queue pointer set, put_disk() also
cleans and releases the queue. This results in blk_cleanup_queue()
accessing an already released data structure, which in turn may result
in a crash such as the following.
This crash is now quite persistent in mainline. The fix didn't make it.
Should I stop testing virtex-ml507 with qemu ?
I've applied the fix now.
But given Michal's comments, should we kill the driver for 5.2?
If the driver is no longer used or maintained, removing it would indeed
make sense.
