I've installed windows and updated bios.

So, before upgrade it was
> [    0.000000] DMI: Sony Corporation SVT1112S1RS/VAIO, BIOS R0140D4 08/23/2012
and now
> [    0.000000] DMI: Sony Corporation SVT1112S1RS/VAIO, BIOS R0150D4 03/13/2013

But really nothing changed. Port still don't work.

I've also checked that this port works fine in pure windows 7 without
any Sony drivers. So it's not a wired hardware issue, it's a bug in
linux kernel. I'll try to test other operating systems like freebsd, may
be port will work there.
