"STOP: 0x0000007F (0x0000000D", unexpected_kernel_mode_trap

[CA707630]

system: DL380G2, 4GB RAM
SA-5304 in slot 2
Adaptec AUA-3020 USB2.0 card in slot 1

Got the trap error above twice in two days.

IML shows this entry:

PCI Bus Error (Slot unknown, Bus 2, Device 0, Function 0)

I can't seem to find what Bus 2 refers to.

Any thoughts?

[Kedd Guyton]

Is there anything in the IML about overheating?

Try reseating all PCI cards and the PCI Riser Card into the system board.

If that doesn't solve the problem, temporarily run the system without the Adaptec AUA-3020 to see if that is it.

[CA707630]

1. IML shows no errors, overheating or otherwise. The highest temp is 43-C for the power supply sensor, with 54-C as the threshhold.

2. I removed the Adaptec and so far no problem - except, of course, now I have no USB2 ports.

Again, what is Bus 2?

[Kedd Guyton]

There are two PCI buses attached to the PCI Riser Card. One is 64-bit/66MHz and the other is 64-bit/33MHz. The documentation doesn't elaborate which PCI slot is on which bus, but it may actually be printed on the back of the server or a sticker on the underside of the chassis cover.

Please check in Device Manager in the properties of the SA-5304. It should list the PCI slot, bus, device, and function. By any chance is the SA-5304 on Bus 2 like shown in the IML's error?

If the server stays up for a while, you may want to consider re-inserting the Adaptec AUA-3020 and checking the Device Manager properties for its bus.

Steps like this should help narrow down the problem.

[CA707630]

DM shows:
5304:
PCI Bus 7, Device 3, Function 0

Standard OpenHCD USB Host Controller:
PCI Bus 0, Device 15, Function 2

PCI standard host CPU bridge:
PCI Bus 0, Device 0, Function 0
PCI Bus 0, Device 0, Function 1
PCI Bus 0, Device 0, Function 2
PCI Bus 0, Device 0, Function 3

PCI standard ISA bridge:
PCI Bus 0, Device 15, Function 0

Looking at everything else on the PCI bus, and all other entries, nothing refers to Bus 2.
I will reinsert the Adaptec when possible but it did not use Bus 2 when installed.

[Kedd Guyton]

Don't forget to Show Hidden Devices. It has to be in there somewhere.

[CA707630]

Yes, I looked at all hidden devices as well and found nothing.

[Kedd Guyton]

That is really strange, but does the system appear to now be stable without the Adaptec AUA-3020 installed?

Which OS are you running?

[CA707630]

Running Win2K Pro SP3.

It appears stable so far, two plus days since the last incident.

Taht incident resulted in the following mess: I was copying 3GB worth of files from a network drive when the error occurred. Upon restart, several open files were damaged but... all the files already copied to this system were *.chk types, as in recovered by the OS. Not several but all of them. That is very strange. I was using the standard Win copy command, not an external program.

We'll see how it goes when I try the Adaptec again today.

[CA707630]

OK, installed a different Adaptec card (same model) and now these devices appear on Bus 2:

Adaptec AUA-3020 PCI to USB Enhanced Host Controller
Bus 2, Device 8, Function 2

NEC PCI to USB Open Host Controller
Bus 2, Device 8, Function 0

NEC PCI to USB Open Host Controller
Bus 2, Device 8, Function 1

IEEE 1394 Bus Host Controllers
Bus 2, Device 9, Function 0

By the way, the card is a 4-port USB2 and 2-port Firewire. Only one cable to a USB DVD player is connected.

Getting there but nothing that completely matches.

[Kedd Guyton]

Did you plug the new Adaptec USB 2.0 card into the same PCI slot as before, PCI Slot 1?

[CA707630]

Yes, of course. Slot 1.
