Using extremely high-tech debugging tools (i.e. spraying printk left and right)
I traced this crash down to:
psci_cpu_suspend_enter: 435
psci_cpu_suspend: 171
psci_cpu_suspend: __invoke_psci_fn_smc c4000001
__invoke_psci_fn_smc: id=c4000001 3 0 0
/*** execution never returns from arm_smccc_smc() ***/
The following dmesg log caught my eye, and might be relevant:
ARM_SMCCC_ARCH_WORKAROUND_1 missing from firmware
Is that bad, doctor? I don't think it would explain the crash though...
If I revert the patch, psci_cpu_suspend_enter() is never called,
so we don't tickle the arm_smccc_smc() monster.
Could it be that this FW doesn't support PSCI?
Regards.
