Possible fix for the reported problem. Please see main text about details. It worked for me, but I am not sure, wether the allocation or deallocation size should be changed. https://bugs.launchpad.net/bugs/1074157/+attachment/3421078/+files/ubuntu-kernel-error.diff |

description |
When going into suspend-to-RAM or suspend-to-disk, I regularly get error messages like this one in the system log and on the console:
[167511.661550] ehci_hcd 0000:00:1d.0: dma_pool_free buffer-128, ffff880036442000/36442000 (bad dma)
There is no crash, just this error message.
I did some debugging of this thing myself by diving into the kernel sources, and ended up with drivers/usb/class/cdc-wdm.c as the likely source of the problem: Allocation and deallocation of DMA buffer space differ on size. Here is the allocation:
desc->inbuf = usb_alloc_coherent(interface_to_usbdev(intf),
desc->wMaxCommand,
GFP_KERNEL,
&desc->response->transfer_dma);
and here is the corresponding deallocation (is in the code twize):
usb_free_coherent(interface_to_usbdev(desc->intf),
desc->bMaxPacketSize0,
desc->inbuf,
desc->response->transfer_dma);
usb_free_coherent(interface_to_usbdev(desc->intf),
desc->bMaxPacketSize0,
desc->inbuf,
desc->response->transfer_dma);
Note, that desc->wMaxCommand is used as the size for allocation, and desc->bMaxPacketSize0 is used as the size for deallocation/free. This should both be the same number. To find out, whether this should read desc->bMaxPacketSize0 in all three places, or desc->wMaxCommand in all three places is beyond my scope, though I'd assume, it is desc->bMaxPacketSize0.

SRU Justification
Impact: dma badness with cdc-wdm, regression introduced by commit
cafbe85 upstream.
Fix: Adjust usb_free_coherent calls.
Test case: it is reported the problem happens on suspend/resume with
cdc-wdm, bad dma messages reported on dmesg
