TX2 kernel shows error for LSI 92xx and m2 to usb2.0, how to?

I worked to add megaraid_sas.ko to support raid. Then it works.
But show errors in dmesg:

[ 53.748742] __arm_smmu_context_fault: 63219 callbacks suppressed
[ 53.748749] arm-smmu 12000000.iommu: Unhandled context fault: iova=0x7ffff000, fsynr=0x210011, cb=21, sid=17(0x11 - AFI), pgd=0, pud=0, pmd=0, pte=0

and m2 to usb2.0 shows:

[ 48.946787] Disabling IRQ #67

kernel source from:
https://developer.nvidia.com/downloads/embedded/l4t/r32_release_v7.4/sources/t186/public_sources.tbz2

I tried but in most .config usb would all offline include wifi and usb3 port.
“irqpoll” causes kernel panic

Hardware works fine.
how to resolve? or disable the message?

Hi,
We would suggest check back trace to debug further. Looks like the driver uses certain already-in-use IRQ and triggers the issue.

ok. The IRQ 67 is not mine. I will check menuconfig.
