Hi Vikram, Joonwoo,
[ + EAS mailing list ]
On Hikey960 with EASv1.3, I encountered many times for WALT panic, it reports the bug from below two functions; you also could see log in the below. Before I dig into this, could you give some suggestion for this? Or if there have some existed fixing for this? Thanks in advance.
I've been running EAS r1.3 kernel for 3 weeks with the default hikey960 defconfig on several hikey960 board, haven't seen this panic yet.
kernel verison: 4a80fc6 ARM64: hikey960: Enable uart3 c5ad7df HACK: clk-hi3660: Fix clk_factor_uart3 to be 100000000, not 200000000 43c93f7 Merge remote-tracking branch 'common/android-4.4' into android-hikey-linaro-4.4-aosp 7eeebce6 ANDROID: binder: Don't BUG_ON(!spin_is_locked()). 78ba0ad Merge 4.4.79 into android-4.4 ...
Does this issue appear frequently?
As Joonwoo meantioned, I have applied patch 426442 [1] so the WALT panic can emerge more obvious; at my side usally I can reproduce this issue within 1 hours for workload testing [2].
