screenshot of error

I am running the 20201105 build of 13 on Raspberry Pi 4. FreeBSD crashed with repeated messages of pager read error. It also says vnode_pager_putpagees: I/O error 6.

The errors do not appear to have been logged anywhere. I'm attaching a screenshot.

This looks like the disk disappeared from underneath the filesystem.  Is it on an SD card?
Comment 2 support 2020-11-19 04:20:02 UTC
Of course, I don't know how else it can be booted. But I'm having trouble accepting bad hardware as the cause versus a bug in v13.
Comment 3 Mark Johnston freebsd_committer 2020-11-23 14:45:35 UTC
This might be a dup of PR 251018, though I do not see any error messages from the sdhci driver to confirm, and that is on rpi3 rather than 4.

I don't have any other ideas.  Of course it may be a software bug, but it's hard to say since there are no driver messages logged in the screenshot.  Has it occurred more than once?  If you scroll up are there any other errors?
