<![CDATA[Netgate SG-2440 / 21.02.2-RELEASE (amd64) / smart status : dev/da0: Unknown USB bridge [0x0424:0x2240 (0x198)]]]>Hello,

On a good old Netgate SG-2440 which received recently the 21.02.2-RELEASE upgrade, I have started to get some crash (about once a week or so) : "page fault".

Now that it happened three times, there clearly is a trend here.

I wanted to check the SMART status of the "disk" device to see if there are signs of wear.

But the page /diag_smart.php returns this when when clicking any of the page buttons (Information - View and others):

smartctl 7.2 2020-12-30 r5155 [FreeBSD 12.2-STABLE amd64] (local build)
Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org

/dev/da0: Unknown USB bridge [0x0424:0x2240 (0x198)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

I don't mind running the command by hand to try to get further information, but I have no idea what device type to pass to -d option.

Also this is probably a bug that it doesn't pass the right command automatically.

Thanks for any idea or pointers.

Seeing the traces were so identical, I checked twice: no confusion, those were two true distinct crashes/reboots.
I had fully removed the good-old trafic shaper right after my last post.
Seeing no new issues for more than 12 hours, I started rebuilding a new shaper configuration. Looks stable for now
Thanks.

Are you sure that's not the same crash?

If not that's definitely the issue. Try disabling shaping if you can.

Looks so much identical. This system gets its WAN over PPPOE, nothing changed on that side (that we know of at least), the box had been rock-solid for so long until it upgraded to 21.02 series from 2.4 series. The shaper was doing a nice job before. Maybe some configuration detail isn't OK with the upgrade. I will turn off the shaper for some time, and see how it goes.

Traffic shaper issue?

Yes, potentially. Combined with something Netgraph is doing, PPPoE?

Really I would wait for it to crash again and compare the backtraces. If they are close to identical then try disabling or changing the traffic shaping.

Got it regarding eMMC/USB/SMART.
The crash looks like this (extract from the crash report on screen). I have the full text too, but did not download the two files (next time I'll do).

You could reinstall to an mSATA drive.

What do the crash reports look like? Near identical backtraces point to a software issue.
