However, can PTP be used while firmware is being upgraded, and what happens if, e.g. bnxt_ptp_enable() were called mid-upgrade? Would that be safe?
This crash happened at boot time, when the kernel was having another at DMA path, which was triggering this bug. There was no firmare upgrade at all. Just rebooting the machine with 6.19 was crashing everytime due to the early failure to initialize the driver.
