Hi,

git bisect revealed that 24180333206519e6b0c4633eab81e773b4527cac is
the first bad commit, which is

"e100: Fix TX hang and RMCP Ping issue (due to a microcode loading issue)"

With it applied, suspend-to-ram fails to resume to userspace, which is
required on my system to get video back (vbetool).
