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(). ...
This means the clocks are not enabled at that point.
WARNING: CPU: 0 ... at drivers/bus/omap_l3_smx.c:166 omap3_l3_app_irq+0xcc/... Tainted: GDW.
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.
I do have patches to allow nfsroot over usb. But they worked ok in v4.9... Does anyone see it, too?
Hmm not much has changed since v4.9. Are you sure you had v4.9 or some earlier v4.9-rc version? Regards, Tony
