      Hi all,

      My Suunto Race 2 has been rebooting constantly — roughly every 10–40 minutes, sometimes as often as every 7 minutes. I pulled the diagnostic logs off the watch’s internal storage to investigate, and the cause is clear and consistent.

      Findings:

      29 crashes recorded in a single 17-hour period
      Every crash is the identical firmware hard fault: HardFault (task:ui), unaligned memory access, at the exact same code address (PC 0x004A0A38) every single time
      Currently running firmware 2.56.18, HW version 1428B4
      A full factory reset did not resolve it — the crashes resumed with the same signature afterward, which rules out a settings/data corruption issue
      A firmware update/rollback attempt around the same time also triggered a separate one-time crash (an internal assertion in the update flasher)
      Given the identical crash address across every occurrence, this looks like a reproducible bug in firmware 2.56.18 itself, not a hardware fault or something caused by my settings.

      Has anyone else on 2.56.18 seen this? Suunto support — happy to share the full log files if useful; I have detailed timestamps, fault codes, and stack traces ready to send. I tried through the app, but I have been sending since the last firmware but they appear to not be fixed so I suspect the ticket is not monitored there.

      Thanks.
