Sleep function called from invalid context. MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7BIT User-Agent: Internet Messaging Program (IMP) 3.2 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org 1. Get call traces from error at startup involving "in_atomic():1, irqs_disabled():0" and "Debug: sleeping function called from invalid context." 2. I receive two call traces at startup. They mention irq_disable(). I do have ISA disabled, since I lack an ISA motherboard. Thankfully this error is non fatal, only annoying. 3. Call traces refers to include/asm/semaphore.h and mm/slab.c. 4.
