I've a suspicion I've seen the first two messages (the DMA ones) but with no ill effect. Whereas the final three are unfamiliar to me and sound more worrying (and hence a better choice for rebooting).
It seems quite normal to have DMA messages (maybe they should be suppressed) but its the last three (the timeout errors) that seem to be related to the slow performance, and thus the eventual file/partition corruption. It's just that it's quicker to determine slow performance (or the lack of it) by writing a file than waiting for dmesg to report that there is (or isn't?) a problem. An SD card that is behaving itself doesn't generate these timeout messages.
