Hi all

I have an rpi pico loaded with micropython and I have this issue detailed on the links below

https://www.raspberrypi.org/forums/viewtopic.php?f=146&t=310648
https://forum.micropython.org/viewtopic.php?f=21&t=10430

It is reproducable on current micropython by others and it seems to be a bug. Please help :)

Tested on 2 Raspberry Pi Pico boards with MicroPython firmware v1.17 to verify behavior

Q Qwen · medium

Both issues affect the RP2 port and involve system hangs/unresponsiveness. However, they describe different root causes and symptoms: Issue #7204 specifically reports a hang when accessing the filesystem while timers/interrupts are active (a race condition/synchronization issue between VFS and interrupt handling). Issue #8137 reports the board becoming unresponsive during long-running sessions (potentially related to watchdog, resource exhaustion, or clock management). While both result in system hangs on RP2, the triggers, affected components, and likely root causes are different. They share the same port but address distinct problems.

Suggested action

Keep both issues open as they address different bugs. The RP2 maintainers may want to review both to determine if there's any underlying common cause, but they should be treated as separate issues.
