I recently upgraded to ubuntu 16.04 and my processor keeps running. I checked top and there's a kworker always running. I checked dmesg errors like the following keep be logged:
[329479.460021] nand: timeout while waiting for chip to become ready [329479.860009] nand: timeout while waiting for chip to become ready [329480.260009] nand: No NAND device found [329480.260023] r852: detected SmartMedia readonly card in slot [329480.524457] r592: IRQ: card added [329480.524466] r592: IRQ: DMA error [329480.604394] r592: IRQ: card added [329480.604399] r592: IRQ: DMA error ...(stack trace)
Any idea of how I can trouble shoot this? I can't decipher the posts on launchpad.
edit: It looks like here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1530187 So is there no fix?
