If I said it unclear, let me repeat, the usermode crash dump you
got probably has nothing common with the kernel issue.
oh sorry. indeed i misunderstood you there. well i guess this is
the problem most regular users have. we don't own any
serial/firewire consoles. all i can offer is to add kernel OPTIONS.
however none of them seem to be able to prevent the lock up and
instead letting me enter the debugger or trigger a kernel core dump.
i even have watchdog running, but without any sucess. i guess all i
can hope for is that maybe at some point a kernel dump does make it
to disk.
Do you have a second box you can run X11 on, and SSH into the box
that will run Chromium? If it is really Chromium triggering the
crash, this might allow you to access the console when it crashes.
However, if it's Chromium triggering an X11-related crash, it might
well not. (Also, it might well not because of timing differences,
but it is worth a try).
Another thing to consider is starting Chromium when switched to a
text virtual console from X11, which would leave you in text mode
for DDB, or at least let you see something interesting on the console.
If regular crashdumps appear unreliable, try setting up a textdump
with an automatic reboot, that might provde more reliable (small
chance, but it could).
we did have some people working on an ethernet version of the
dcons/remote debugging stuff
I guess it only supports a small subset of ethernet chips though..
Anyone know the status of that work?
