I'm seeing some curious 2.1.x behaviour with an interrupt handler for the Z85230 sync driver Im currently working on
If I make any user of save_flags/cli/restore_flags or the equivalent spinlock_and_save* functions within the driver the instant it hits the restore_flags it apparently re-enters the interrupt repeatedly blows the entire stack and dies with an oops about 250 pages long
2.1.108 uniprocessor and tested on two different systems.
