Re: Brief report: QNAP TS-212P with linux-image-kirkwood 4.0.0-2

Yes, I managed to catch it in the act:

http://pastebin.com/PYqqrcLX

Basically, the device stalls during the flashing process (which takes maybe three minutes), and that seems to cause sata to time out, and eventually everything gets remounted read-only. Now if I recall correctly, I'd get sata link timeouts with 3.16 as well, but it behaved more gracefully (reset a couple of times and was back in business after the flashing was done).

Best regards,

Jan

This is a bit worrying. The device with /tmp and /var/lib/dpkg on is
presumably not on the flash itself (that's too small), so the fact they
go r/o at some point here is quite strange.

Are there any incriminating messages in dmesg?
