Hi again,
I was abble to reproduse the reboot/shutdown when I close h-e-n, BUT only when I'm overclocked above 600MHz ( Tried with different frequencies alway the result is the same - shutdown or reboot when I close h-e-n)
How to reprodusce the issue:
(Have installed klogd and sysklogd before - rebooted N900)

1.Installed kernel - 2.6.28.10.power44
2.Installed QCPUFreq v. 0.4.0, from settings enable overclocking - change frequency to more than 600MHz close.
3.Check with Conky actual max frequency
4.Start h-e-n (v. last one - mount/unmout implented) :
-close h-e-n - resul reboot
-pres High Speed hostmode, VBUS boost on Enumerate - successful enumeration, VBUS noost off, close h-e-n - result shutdown.
tried 5 time always have shutdown/reboot when OC, when I'm not over 600MHz no problem with shutdown/reboot after close h-e-n

this is only report (unconfirmed - if someone willing to try and report). I usually do not do overclock and is not issue for me.

attaching my logfile in case you want to have a look.

AI also have e question ( not retailed to the writings up) - When I connect USB flash drive sometimes it gets enumerated right away, but sometimes it took a while to enumerate? Is this known issue with the beta driver or something else? Does someone else experience the same 'x' wait time until Flash drive (or device connected) get enumerated? Am I alone?
Tried with different devices it is the same with stock and power kernel.
