[BUG] Hard-fault with PX4 1.14.1 and NuttX v11.0.0

[TyrolianTurnip]

Describe the bug

1.06.24 : In almost every flight we get a [load_mon] nsh_main low on stack! (180 bytes left) warning related to the NuttX shell in our px4 logs every odd 30 seconds.

31.07.24 : The PX4 had a hard-fault and rebooted during ground maintenance after power cycling a battery indirectly connected to it via a RaspberryPi over USB. As a result, the local time reset in the CAN FcsLocalTimePacket between 7365 and 7380 seconds, following the disconnection of the batteries at t=7343s. Consequently, it is assumed that a stack overflow might have occurred due to a spike in usage of '/src/px4/platforms/nuttx/NuttX/nuttx/drivers/usbdev/cdcacm.c'

01.08.24 : Assuming that the hard-fault was caused by a stack overflow, our current mitigation strategy involves manually increasing the stack size from CONFIG_INIT_STACKSIZE=2944 to CONFIG_INIT_STACKSIZE=3194 in line 115 of px4/fmu-v5/nuttx-config/nsh/defconfig, as has been done in PX4 1.15.1 and as a fix for earlier hard-faults (#11703). Doing so had removed the occurence of [load_mon] nsh_main low on stack! (180 bytes left) warnings, but we would like to understand the root cause of this error better to be ensure that it never occcurs during flight.

Feedback on this issue and a fix would be much appreciated!

To Reproduce

Power cycle a Raspberry-pi connected the the PX4 via USB for the hard-fault, leave it connected for the warnings.

Expected behavior

No warnings or hard-fault
