e1000e: Disabling IRQ #57 .. machine dies

Hi:

In current linus tree, in a machine using the e1000e driver

hwinfo --netcard
22: PCI 400.0: 0200 Ethernet controller
[Created at pci.319]
Unique ID: rBUF.cuT2KaC3ZS1
Parent ID: HnsE.Z52SDLRIaH2

Device: pci 0x10d3 "82574L Gigabit Network Connection"
SubVendor: pci 0x1043 "ASUSTeK Computer Inc."

Driver: "e1000e"

Module Alias: "pci:v00008086d000010D3sv00001043sd00008369bc02sc00i00" Driver Info #0:
Driver Status: e1000e is active
Driver Activation Cmd: "modprobe e1000e"
Config Status: cfg=no, avail=yes, need=no, active=unknown Attached to: #15 (PCI bridge)

cat /proc/interrupts

57 IR-PCI-MSI-edge eth0

the driver works after a while, but then a single message

"Disabling IRQ #57"

is sent to the console and the machine dies, nothing else is written in the logs and remote ikvm becames unresponsive so there is no way to bring more debug info back.. kernel 3.5.3 works ok.

Anyone else seeing this ?

Hello,

I'm sorry you're having problems with out parts. Can you provide some more info on this issue? What version of the driver are you using? Is the only problem that this driver dies or are there other symptoms? What does the dmesg say for the e1000e driver at load? It usually list whether its using MSI/MSI-X, and some other info. Can you provide an lspci -vvv output for the 82574L device and the dmesg info? Is the "Disabling IRQ #57 message appearing in the dmesg log or somewhere else? Can you try loading the driver with the module parameter IntMode=0 to try the device in legacy interrupt mode, if its not already in that mode.

Thanks,

Carolyn
