Hi Wang,
A bug was opened against the Ubuntu kernel[0]. After a kernel bisect, it was found that reverting the following commit resolved this bug:
commit 8d2f8cd424ca0b99001f3ff4f5db87c4e525f366 Author: Wang YanQing <udknight@gmail.com> Date: Fri Mar 1 11:47:20 2013 +0800
serial: 8250_pci: add support for another kind of NetMos Technology PCI 9835 Multi-I/O Controller
The regression was introduced as of v3.9-rc3 and still exists in the current Mainline tree. It was also propagated to the stable trees.
The patch causes the device to use the serial module instead of parport_serial. Maybe the the quirk in ~drivers/pci/quirks.c quirk_netmos() needs to be modified?
I see that you are the author of this patch, so I wanted to run this by you. I was thinking of requesting a revert, but I wanted to get your feedback first.
Thanks,
Joe
