Subject: [ath9k-devel] DMA read errors on wpea-127n
Date: Mon, 10 Dec 2012 19:55:14 -0800 [thread overview]
Message-ID: <50C6AEA2.4050508@candelatech.com> (raw)
This is with the 3-radio (wpea-127n) system, kernel 3.5.7+
200 virtual stations per radio..seems it cannot really handle
this well. I'm seeing the errors below on at least two of the
radios...
DRHD: handling fault status reg 3
IPv6: ADDRCONF(NETDEV_CHANGE): sta600: link becomes ready
sta604: deauthenticating from 00:a2:d2:b3:c3:01 by local choice (reason=3)
DMAR:[DMA Read] Request device [04:00.0] fault addr 0
DMAR:[fault reason 06] PTE Read access is not set
sta66: deauthenticated from 00:89:89:00:01:89 (Reason: 7)
I'm low on ideas for how to debug this :P
Thanks,
Ben
