Still happens on the current torvalds/master.
Due to this bug it is not possible to use btrfs on top of a dm-crypt device with no_read_workqueue and no_write_workqueue flags enabled.
@Ignat: Can you have a look at this as the person who added these flags?
It looks like to me that the skcipher API might not be safe to call from a softirq context, after all.
