For relatively short (tens of seconds or so) periods of time, kernel
successfully draws 1000mA from usb bus. according to measurements with
multimeter charge current is >500mA.
Sign of this event is
[ 6.500000] pcf50633 0-0073: usb curlim to 1000 mA
[ 47.680000] pcf50633 0-0073: usb curlim to 500 mA
Mean that while booting 1000mA drawn for 41 seconds.
Similar situation happens on suspend, but this were only visible while i
added delay to printks for debugging.
Tested for om-gta02-34 kernel from git. I think similar thing happens with
other kernels too.

Comment(by lindi):
On andy-tracking a3587e4ed77974ad
1) reboot
2) dmesg|grep -i cur
prints
2)
[21474541.975000] pcf50633 0-0073: usb curlim to 100 mA
[21474557.790000] pcf50633 0-0073: usb curlim to 500 mA
so I guess the problem was introduced after that commit?

Comment(by gena2x):
Git is not linear system, so term 'after' may not be applied to different
branched. Also, this problem may be triggered with different things, like
kernel config.
I think i saw this also for andy-tracking optimized for speed.
