| Yes, I just did some testing. The phone had been on for about 12 hours
maybe
| and had gone through multiple suspend-wakeup cycles. TTFF was around 10
| minutes. Then I switched off the phone and switched it back on, after
that
| TTFF was about 40 seconds.

| Now that I came back indoors, the phone still has a fix and with older
kernels
| it could not keep the fix if I went indoors. So it seems the software fix
| isn't perfect yet (it can't "recover" from suspend or something), but
if you
| always "start fresh", it does work well.

Thanks for this report, I went and looked and found I didn't take care
of the case where last packet transferred was not a bulk read packet:
that what happens on resume.  I added a patch to stable branch that
should be out tomorrow hopefully and give the same SD_CLK performance
with or without resumes.
