Dear,

On Q1900TM-itx mb with the same BIOS setting

14.04.1 shows with at /proc/acpi/wakeup
Device  S-state   Status   Sysfs node
XHC1      S4    *enabled   pci:0000:00:14.0
PXSX      S4    *enabled   pci:0000:01:00.0
PXSX      S4    *enabled   pci:0000:02:00.0
PXSX      S4    *disabled
PWRB      S0    *enabled

14.04.3 shows cat /proc/acpi/wakeup
Device  S-state   Status   Sysfs node
UAR1      S4    *disabled
XHC1      S4    *enabled   pci:0000:00:14.0
EHC1      S4    *disabled
PXSX      S4    *disabled  pci:0000:01:00.0
PXSX      S4    *enabled   pci:0000:02:00.0
PXSX      S4    *disabled
PWRB      S0    *enabled   platform:PNP0C0C:00
BRCM      S0    *disabled 
BRC3      S0    *disabled

==> IN consequence,  WOL is perfectly working on 14.04.1 and absolutlty nothing in 14.04.3
Trying to disable -> enable by ECHO PXSX > proc/acpi/wakeup . but the system dosn't allow !!!

Could you support me ? 
Thanks in advance for your precious help
