Same behavior without maxcpus=1 40 boots, no panics, no FSYNR other than 16c0000.iommu > The thing will likely run slower (because reasons), but shouldn't > explode That makes sense! - Hey, boot is slow. What can we do to make it slower? - Well, just add a bunch of cores running in parallel, that will get the job done! As a matter of fact, trying to boot to command-line with maxcpus=1 causes the system to lock up & reboot. I had to add a systemd script to enable some cores at init. Some qcom daemon must be locking a core & expect progress from another process. Regards
