[fedora-arm] Trimslice SSD issues

[Jon Masters]

Hi again Konstantin,

A number of folks in the Fedora ARM community are experiencing problems
with the Trimslice internal SSD dropping off the USB bus following a
forced bus reset (we are unclear why this happens under load). This
sometimes results in the SSD going readonly, or disappearing entirely.
Either way, it means that we can't use the SSD for e.g. building gcc.

Can you take a look at the example logs attached? To reproduce, using an
F15 hardfp rootfs running from an SD card, mount the SSD and build a
package such as gcc (recommended) from there. This avoids the entire
system falling over when the SSD drops, but allows for a reproducer.

Since this only happens under load, I'm hoping you will tell us there is
a software fix, or that it is heat related, or otherwise addressable.
Either way, we would like to know. Especially if it's a known issue.

Thanks!

Jon.
