37	R8169 and Lenovo ThinkPad L530	Doug Bissett	David Azarewicz	"I got a new Lenovo ThinkPad L530. It has a Realtek ""Device 8168h RTL8111/8168B PCI Express Gigabit Ethernet controller in it"" (from PCI.EXE). I tried Multimac from r8169-0.2.1.wpi. It loads okay, and most of the time, it will get an address from my router, using DHCP. However if I actually try to use it, the machine hangs hard. The only option is to force a power off. I also tried the older multimac driver (R8110), but it hung hard when the driver loaded. I then tried two GENMAC drivers, with no success. The driver from rtgnda13.zip does work, but seems to have a couple of minor problems. Of course, it works perfectly in Win7 Pro 64.

By ""actually try to use it"", I mean: I loaded Firefox (10.0.12esr), which has a home page of a file on my system. As soon as I try to go to a URL on the internet, I see the Pulse widget indicate about 60% IRQ load. That lasts for about 5 seconds, then the machine is locked. The mouse won't even move. The only way out is forced power off. I also, eventually, see the 60% IRQ load, if I just let the machine sit idle (probably the router doing something), followed shortly by the hard hang.

I traced the operation on my router, but all it shows is the initial connection, which succeeded.

I loaded the TRACE R8169 driver, but since the machine is locked, I can do nothing with it. I did take a trace after a reboot, without actually trying to use the network interface (not sure if it will help).

PCI.EXE output is in L530.txt. I included the whole thing, since this is a relatively new machine, with UEFI BIOS.

Trace output is in L530_10EC_8168.ftf.

Probably useless information: I did find a hit (that I can't find again) that sounds exactly the same in SUSE linux. It mentioned that UBUNTU linux does NOT have the problem."	defect	closed	major	r8169		fixed
