After lots of experiments I found out that the problem is with the
xhci_hcd module. The strange thing is that other people with the same
laptop model didn't encounter the same issue. The following script fixed
it (placed under /etc/pm/sleep.d/):
EHCI_BUSES="0001:00:1a.0 0000:00:1d.0"
XHCI_BUSES="0000:04:00.0"
case "${1}" in
hibernate|suspend)
# Switch USB buses off
for bus in $EHCI_BUSES; do
echo -n $bus > /sys/bus/pci/drivers/ehci_hcd/unbind
done
for bus in $XHCI_BUSES; do
echo -n $bus > /sys/bus/pci/drivers/xhci_hcd/unbind
done
;;
resume|thaw)
# Switch USB buses back on
for bus in $EHCI_BUSES; do
echo -n $bus > /sys/bus/pci/drivers/ehci_hcd/bind
done
for bus in $XHCI_BUSES; do
echo -n $bus > /sys/bus/pci/drivers/xhci_hcd/bind
done
