Comment 1 Stanislaw Gruszka 2011-12-31 12:52:36 UTC 
We indeed map stack memory for DMA in logi_dj_recv_switch_to_dj_mode() and logi_dj_recv_query_paired_devices(). But I do not see why this is a problem, we wait until DMA finish before we exit from both functions ...
Comment 2 Martin Kho 2012-01-03 11:57:39 UTC 
Just booted my fedora 17 test OS

Package: kernel
OS Release: Fedora release 17 (Rawhide)
Comment 3 Martin Kho 2012-01-07 16:34:28 UTC 
Hi,

For me, this issue only occurs when I switch from kernel 3.1.x (Fedora 16) to 3.2.x (Fedora 17) c.q. usb-generic driver to hid_logitech_dj driver and had total system freezes after reboot from 3.2.x to 3.1.x. Reboots from 3.2.x to 3.2.x and from 3.1.x to 3.1.x are okay.

Comment 4 Martin Kho 2012-01-09 13:45:22 UTC 
Hi,

With the latest kernel (3.2.0-2.fc17.x86_64) I don't see the DMA message. So, for me at least, it seems to be solved.

Thanks,

Martin Kho

No, that kernel just has the debug options disabled so the warning goes away.  The underlying problem is still present.
Comment 6 Stanislaw Gruszka 2012-02-26 12:26:42 UTC 
Actually I do not think there is any problem here. We use stack memory for DMA, but we wait on function that allocate stack until DMA finish. So this time issue is a DMA API debugger false positive.
