On a fresh boot, the MMC/SD memory card reader on my laptop works fine. However, if I hibernate and resume my laptop and attempt to use the MMC/SD memory again, the laptop fails to read the memory card and I receive a kernel trace from the driver.
The kernel trace is as follows: [208991.375755] irq 21: nobody cared (try booting with the "irqpoll" option) [208991.375761] Pid: 0, comm: swapper/1 Tainted: G W 3.3.4-030304-generic #201205011755 [208991.375764] Call Trace: [208991.375774] [<c10b38a9>] __report_bad_irq+0x29/0xd0 [208991.375780] [<c1572bff>] ? _raw_spin_lock_irqsave+0x2f/0x50 [208991.375784] [<c10b3a63>] note_interrupt+0x113/0x1c0 [208991.375788] [<c10b17f9>] handle_irq_event_percpu+0xa9/0x1e0 [208991.375793] [<c10279b8>] ? default_spin_lock_flags+0x8/0x10 [208991.375797] [<c10b196b>] handle_irq_event+0x3b/0x60 [208991.375800] [<c10b4010>] ? handle_percpu_irq+0x50/0x50 [208991.375804] [<c10b405e>] handle_fasteoi_irq+0x4e/0xe0 [208991.375806] <IRQ> [<c157a272>] ? do_IRQ+0x42/0xc0 [208991.375815] [<c1065ad2>] ? sched_clock_local+0xb2/0x190 [208991.375819] [<c157a1b0>] ? common_interrupt+0x30/0x38 [208991.375823] [<c106007b>] ? find_process_by_pid+0x2b/0x30 [208991.375828] [<c131e643>] ? acpi_idle_enter_simple+0xef/0x12a [208991.375834] [<c1458d2b>] ? cpuidle_idle_call+0xab/0x1d0 [208991.375838] [<c10020b4>] ? cpu_idle+0xa4/0xf0 [208991.375841] [<c156c271>] ? start_secondary+0xf1/0xf7 [208991.375844] handlers: [208991.375848] [<c13eaba0>] usb_hcd_irq [208991.375866] [<f83b9710>] sdhci_irq [208991.375871] [<f8881780>] r592_irq [208991.375875] [<f8a5c6b0>] r852_irq [208991.375877] Disabling IRQ #21 [208998.208046] mmc0: Timeout waiting for hardware interrupt.
