Subject: Computer stalled, apparently from filesystem corruption
Date: Thu, 10 Mar 2022 05:56:35 -0500 [thread overview]
Message-ID: <12976593.dW097sEU6C@puma> (raw)
Sending again, with less syslog. I wrote this on the 8th.
My computer was up for several months. On Saturday I came home from church and
found it unresponsive except that I could move the mouse cursor and make the
keyboard lights blink. I tried to shell in from another computer; I got a
connection, but not a login prompt. I rebooted it with the power button and
copied the syslog file that contains the incident. I saw "btrfs" several times
in the section of log.
This morning, I was rsyncing some files and the same thing happened, except
that the screen was stuck in the middle of flipping through windows with alt-
tab and I was able to switch to a console, log in as root, and reboot. Again I
found "btrfs" in syslog.
Running dmesg produces too much information. Here is the rest of the info:

The kernel I was running on Saturday may be older.
