Sorry I couldn't see the part before the bt. I just started up the console and everything looked good with my login prompt. After I put in the admin username I saw the db> prompt…

None of that looks familiar, unfortunately. There had been a few 2.0 panics over the last few months but they were all resolved, this one looks new. It seems to have crashed in two dissimilar code paths as well even though the begin and end the same. One seems to involve netgraph (PPPoE on WAN? PPTP or L2TP server active?) and the other doesn't.
Do you have anything plugged into the ALIX USB ports? It's odd that ucom is showing up there, that's the USB com port driver.
What kind of features do you have going on this setup? Any services or VPNs enabled? Packages installed? Traffic Shaping?
-
A I have a usb to serial adapter connected to the beast ;) Maybe I should disconnect it from my mac when I am not using it…
-
Check the output of "vmstat -i"
I wonder if your usb adapter is sharing an IRQ with a network card, which seems like a recipe for disaster on a low power device.
-
Hi!
This is the output…
interrupt total rate
irq0: clk 120917 99
irq4: uart0 501 0
irq8: rtc 154794 127
irq9: ath0 73851 61
irq10: vr0 6349 5
irq11: vr1 9958 8
irq12: ohci0 ehci0 1 0
irq14: ata0 11966 9
Total 378337 312 -
That looks fine, though is that with or without the USB serial adapter plugged in?
I suppose it may just be a coincidence that it's the irq process that is active when the panic happens, but it's hard to say for certain.
-
This was taken with the usb adapter inserted. But it is usb on the Macintosh side. It is still serial on the Alix…
-
ahh… well then that wouldn't explain the ucom then. The ALIX would only see serial, not a USB device on its end.

And again. This is the last things I could grep:
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 11 (irq10: vr0) -
Okay. Now again. I am testing igmpproxy right now, perhaps it has something to do with it?

Possibly. Did it happen at all before you started testing it?
We'll get Ermal or someone to take a look at the backtraces when time permits.
-
Yeah, the first two happened before I think. But at least the first. All the ones from yesterday happened when I tested the igmp proxy…
-
Another one again. But I can only see stuff starting with the prompt most of the time….

Do we have any info yet? Today this happened again and I really would like to know what this is. I can simply install 1.2.3 again and wait until 2.0 is out of beta, but I want to help the project. So devs, what could be the problem? Anything else I should check?
-
Would you guys please be so kind to give me an answer. Otherwise it is no fun posting these backtraces…
Today it happened again... -
Unfortunately with the snapshot server out of commission until the new one is put in place there isn't much to do or try except keep track of the traces.
-
Yeah well but this doesn't answer my question what the real problem is. Or do you think that these problems were silently fixed in a new snapshot?
