BUG: scheduling while atomic: exe/0x00000101/752
Yup, you can't sleep in taskets, they're atomic.
caller is schedule+0x4c/0xe4
Call trace:
[c02dc4dc] __schedule+0x654/0x788
[c02dc6f4] schedule+0x4c/0xe4
[c02dbe24] __compat_down+0xc8/0x12c
So, you can't use / acquire semaphores in them. Use spinlocks.
If the shared data is also accessed from process context, use
spin_lock_bh() from the process context code.
