| |
Hey Folks, I noticed with linus/master wifi wasn't coming up on HiKey960. I bisected it down and it seems to be due to:
60f36637bbbd ("wlcore: sdio: allow pm to handle sdio power") and 728a9dc61f13 ("wlcore: sdio: Fix flakey SDIO runtime PM handling")
When wifi fails to load, the only useful error message I see is: [ 8.466097] wl1271_sdio mmc1:0001:2: wl12xx_sdio_power_on: failed to get_sync(-13)
Reverting those two changes gets wifi working again for me: [ 8.754953] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11) [ 8.761778] random: crng init done [ 8.765185] random: 7 urandom warning(s) missed due to ratelimiting [ 8.779149] wlcore: loaded ... [ 12.945903] wlcore: PHY firmware version: Rev 8.2.0.0.237 [ 13.058077] wlcore: firmware booted (Rev 8.9.0.0.70)
Any suggestions how to resolve this w/o a revert?
thanks -john
