Looking at the log, I noticed the EEH is frozen right after finding the Broadcom card. Is that one the tg3?
[ OK ] Found device NetXtreme BCM5719 Gigabit Ethernet PCIe. [ 8.191135] EEH: Frozen PE#7 on PHB#21 detected [ 8.191280] EEH: PE location: S00210f, PHB location: N/A Also, the recovery problem seems to be caused by ast. [ 18.267005] EEH: 2100000 reads ignored for recovering device at location=S00210f driver=ast pci addr=0021:10:00.0 [ 18.267334] EEH: Might be infinite loop in ast driver Looking at the upstream logs, one commit came up. Can you open a new bug for it? commit 298360af3dab45659810fdc51aba0c9f4097e4f6 Author: Russell Currey <[email protected]> Date: Thu Dec 15 16:12:41 2016 +1100 drivers/gpu/drm/ast: Fix infinite loop if read fails ast_get_dram_info() configures a window in order to access BMC memory. A BMC register can be configured to disallow this, and if so, causes an infinite loop in the ast driver which renders the system unusable. Fix this by erroring out if an error is detected. On powerpc systems with EEH, this leads to the device being fenced and the system continuing to operate.
