Sone033 Fixed [repack]

Once you have applied the fix, maintain stability by avoiding "beta" versions of the software unless absolutely necessary. Regular backups of your configuration files will also ensure that if the error recurs, you can restore your settings in seconds rather than performing a full manual fix.

The TIMER0 register’s fixed‑point representation makes it particularly vulnerable to fractional overflow. Traditional overflow checks (e.g., saturating counters) are insufficient because a missing increment can shift the fractional part, causing the integer portion to under‑flow—exactly what happened in SONE033. The idempotent update strategy preserves the invariant that the fractional part never loses a tick, guaranteeing deterministic watchdog behavior.

A test board containing the revised silicon (revision R2.1) was exercised with a dual‑DMA stress generator that pushes two channels at 100 % bus utilisation.
