When I got back to the phone, it was dead...

I hooked it up to my computer, but was unsure if it was already
correctly enumerated. Apparently it wasn't, and 100mA is certainly not
enough to remain warm!

Post-mortem is not possible, I guess...

Here's the current info, and boy, was it empty...

Anything else that might have been of value :-) ?

I'll try to reproduce tomorrow (Wifi ON, GPS ON) and check if I can
get these values out...

Too bad.

Nope, it's a V6 (AFAIK), so it doesn't stay up without a battery.

I've seen lots of stuff come by on the mailing list.

OM2008.12 doesn't support a newer kernel, does it?

I'm not against installing Qi and a 'stable' or 'tracking' kernel,
since I don't use it for 'daily use' yet...

So, are there any steps to take to reproduce this, and/or check if it
still happens with newer kernels?
