Subject: Re: [BUG, regression, bisected] Marvell 88E8055 NIC (sky2) fails to
 detect link after resume from S3

Breaking news:
Fiddling with mmiotrace, I was able to get the "phy I/O error" on
previously-thought-good kernel (non-reliably; it took several
suspend-resume cycles), and also vice versa - in vty, I was able to
suspend and resume the "bad" kernel with the NIC still working (also
not reliably - in GUI, it still flaked out after first
suspend-resume).

Anyway, I've gathered traces of both good and bad behaviour, each from
the respective kernel (not that it seems to matter much). Now, what's
the recommended way of posting them? Each is over 3MB in size and
pastebin won't take them. :-(
