Hello, I have been seeing a regular occurrence of DMAR errors, looking something like this when testing my ath10k driver/firmware under some specific loads (maximum receive of 512 byte frames in AP mode):
DMAR: DRHD: handling fault status reg 3 DMAR: [DMA Read] Request device [05:00.0] fault addr fd99f000 [fault reason 06] PTE Read access is not set ath10k_pci 0000:05:00.0: firmware crashed! (uuid 594b1393-ae35-42b5-9dec-74ff0c6791ff) So, I am wondering if there is any way I can get more information about what this fd99f000 address is? Once this problem hits, the entire OS locks hard (not even sysrq-boot will do anything), so I guess I would need the DMAR logic to print out more info on that address somehow.
