Logs are so limited. If possible, revert below commit and give a try "ath10k: do not use coherent memory for allocated device memory chunks"
If revert is not so clean, try with this patch. https://patchwork.kernel.org/patch/9175029/ -Rajkumar ________________________________________ From: ath10k <[email protected]> on behalf of Ben Skeggs <[email protected]> Sent: Friday, July 8, 2016 10:59 AM To: [email protected] Subject: AR9882 IOMMU faults Hey, I've just installed a COMPEX WLE600VX (AR9882) in my router machine, operating in AP mode. While it appears to be working well enough, I get massive floods of IOMMU faults reported in my kernel log. These appear to increase with the load on the network. I've attached both the info that ath10k reports when it detects the device, and a sample of one of the DMAR messages (worth nothing that it's the same fault address in all the messages). Is this a known issue, and anything I can do to help get it resolved? Thanks, Ben. _______________________________________________ ath10k mailing list [email protected] http://lists.infradead.org/mailman/listinfo/ath10k
