Subject: Regression: Wake up from Suspend to RAM crashes Toshiba Satellite
laptop to black screen
Hi, Hayes,
We got a regression report complaining that wakeup from Suspend to RAM
crashes, please refer to
https://bugzilla.kernel.org/show_bug.cgi?id=82741
and it seems that it is introduced by commit
b51ecea852b712618796d9eab8428a7d5f1f106f.
Date: Wed Jul 9 14:52:51 2014 +0800
r8169: disable L23
For RTL8411, RTL8111G, RTL8402, RTL8105, and RTL8106, disable the
feature
of entering the L2/L3 link state of the PCIe. When the nic starts
the process
of entering the L2/L3 link state and the PCI reset occurs before the
work
is finished, the work would be queued and continue after the next
the PCI
reset occurs. This causes the device stays in L2/L3 link state, and
the system
couldn't find the device.
