It seems to work all right. But I thought it was due to someone of theese options:
+CONFIG_IRQ_FORCED_THREADING_DEFAULT=y
-CONFIG_INLINE_SPIN_UNLOCK_IRQ=y
-CONFIG_INLINE_READ_UNLOCK=y
-CONFIG_INLINE_READ_UNLOCK_IRQ=y
-CONFIG_INLINE_WRITE_UNLOCK=y
-CONFIG_INLINE_WRITE_UNLOCK_IRQ=y
It seems to work all right. But I thought it was due to someone of theese options: IRQ_FORCED_ THREADING_ DEFAULT= y INLINE_ SPIN_UNLOCK_ IRQ=y INLINE_ READ_UNLOCK= y INLINE_ READ_UNLOCK_ IRQ=y INLINE_ WRITE_UNLOCK= y INLINE_ WRITE_UNLOCK_ IRQ=y
+CONFIG_
-CONFIG_

It seems I was wrong.
