Default USB key installed OS; file system goes read-only randomly...

This happened a few times now, I (soft) reboot and do the fsck thing and all is
fine until it happens again.

Any ideas?

...

note that /var/log/dmesg is just a snapshot of the output of the program
dmesg taken after boot time. the dmesg command dumps the current
kernel message buffer, but I don't believe it has a live 'follow' mode.

that said, most stuff written to the kernel message buffer gets
processed by syslog and put in /var/log/messages

A) your USB key is flakey

B) your systems USB ports are flakey

C) the cabling between the mainboard and the USB port is flakey.


I've run into C) quite a lot, where front panel USB ports don't work
reliably at USB2.0 speeds when doing large and/or complex operations. I
suspect the internal wiring is inadequate for the task.
