Greetings,
I've encountered a problem, where an external USB flash drive starts giving read errors when host is left sitting idle, about 13 hours after boot, in this particular case, according to the logs:
This is a nanobsd installation, and since root file system is on this flash drive the OS gets unusable. However host boots successfully if restarted and
That being said, next to this problem host there is another physical host, with different hardware configuration and different flash drive, but running mostly the same nanobsd install for more that 4 days, with no problems at all.
Is it possible this, fairly old, 4GB Kingston flash drive to be confused after entering powersave mode and can it be recovered/reconnected somehow, if so?
Is it possible to disable powersave mode for this specific USB flash drive or for USB mass storage subsystem at all?
Any suggestions on how to test if a particular flash drive can survive powersave -- i.e. to manually force a device to enter powersave mode?
Any other suggestions are also welcome!
Thank you!
