Today while working feverishly I have had my MBP shutdown 3 times for no apparent reason. The power adapter is plugged in and I am using the wired ethernet.
The shutdowns occurred when I had wandered away from the machine for a few minutes and not actively using it. I have no sleep mode set to kick in when the power is plugged in and the last time it happened was during a 3 minute phone call (I checked my phone to be certain).
About an hour I lost network connectivity all together. I checked ipconfig and it was reporting I had a 169.* ethernet address. This is the default when it can’t contact a DHCP server. After renewing my DHCP lease a few times I gave up and rebooted. This did the trick.
On digging through the logs I see this…
kernel[0]: ar5212GetPendingInterrupts: fatal error, ISR_RAC=0x8402c ISR_S2_S=0x10000
kernel[0]: AppleYukon: error – Uncorrectable PCI Express error
Has anyone else experienced this?
I found a couple hits on google but nothing with a definitive resolution.
