Hi!
I forgot I had v4.10-rc1 running, and now I got warning on all the
consoles (hand-copied).
Unhandled fault: external abort on non-linefetch (0x1028) at
0xfa0ab060
...
Comm: kworker/0:0 Not tainted.
Workqueue: events musb_irq_work
...
PC is at musb_default_readb().
...
WARNING: CPU: 0 ... at drivers/bus/omap_l3_smx.c:166
omap3_l3_app_irq+0xcc/...
Tainted: GDW.
I do have patches to allow nfsroot over usb. But they worked ok in
v4.9... Does anyone see it, too?
Best regards,
Pavel

This means the clocks are not enabled at that point.

If you comment out postcore_initcall_sync(omap3_l3_init);
in drivers/bus/omap_l3_smx.c you'll see the proper stack
trace instead of the l3 interrupt trace. The system will
hang at that point most likely.

Hmm not much has changed since v4.9. Are you sure you
had v4.9 or some earlier v4.9-rc version?

I believe v4.9 works.
But... this may be tricky to reproduce. It happened once so
far... after I reconnected N900 to computer when it was running for a
while. I do have USB cable with power meter on it, thus "flakey". Lets
see if it reappears...

It happened again in -rc5. I have full dmesg this time.
I started new thread with "
Subject: v4.9 to v4.10 regression: oops when USB cable is plugged in.
". It does no longer look completely scary.
