That sounds like a bug where a loop counter isn't initialized correctly, so a loop wraps around and has to go through the whole range of a 32 bit int until it terminates, i.e. 2^32 which is 4 billion interations. Depending on what the loop actually contains, that could very well take 5 minutes. There have been bugs like that in the past. If you enter the Debugger during the hang and print a stack trace, you should be able to see where that loop is. Maybe it's easy to spot the incorrect loop counter and fix it. > > > I tried using loader hint hint.usb.2.disabled="1" but it doesn't > > > work. > > > > Unfortunately, hints cannot be used to disable devices in > > general (which would be a desirable feature).

Yes, that's what I mean. I'm sure it could be useful. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
