Our kernel randomly crashed,most of the time there is no backtrace infomation. the kernel log as folllows:
[ 910.832322] bwmgr: clk_set_rate failed for freq 18446744073709551506 Hz with errno -22 [ 911.836349] sdhci-tegra 3460000.sdhci: clock enable is failed, ret: -110 [0000.277] I> Welcome to MB2(TBoot-BPMP)(version: 01.00.160913-t186-M-00.00-mobile-f4c42291) [0000.285] I> Default Heap @ [0xd486400 - 0xd488400]
We want to know the meanning of bwmgr, does is means band width manager? What causes the kernel to crash when the printed message appears?
