NRF54L15 k_uptime_get() return strange value

[kyozc]

Hi Dev,

Development platform: NRF54L15 + NCS 3.0.2. We use k_uptime_get() to obtain the system uptime and perform task scheduling. Everything runs normally when the device is first started, but after the device runs unattended over the weekend, k_uptime_get() returns a strange value of 590295789593661 ms, causing the entire system timestamps to become disordered. Rebooting does not resolve the issue; the device must be powered off to restore k_uptime_get() to normal. What could be the cause of this issue?  This issue is not consistently reproducible.

Thanks
