Hello, I'm running 2.6.39 on omap3530 with a number of patches and am seeing the below crash on suspend. Questions:
1) does anyone have musb suspending with 2.6.39? 2) are there any fixes or suggestions? Thanks, Cliff musb-hdrc musb-hdrc: suspend Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa0ab00c Internal error: : 1028 [#1] PREEMPT last sysfs file: /sys/power/state Modules linked
