[DragonFlyBSD - Bug #2244] usb - system hangs during boot when USB mass storage device/stick is connected - 2.13.0.357.gcdb8af

Issue #2244 has been updated by Alan K.


I tested with dfly-x86_64-2.12.0_RC.img. It doesn't have the problem. 

This led me to test different stages of the master branch.

The problem appears to first start with commit 7e370202e053de3ef8357ef02e8b6f1e97694f97

The problem does not occur before that commit (i.e. with 95874ffdec65823430464b7869d8f0acf75cc226 or older).

Problem Description:

My system hangs during boot if a USB mass storage device/stick is connected.
By hang I mean no more output is shown and I cannot turn off/on num lock key on keyboard.
A hard reset is needed at this stage.

This prevents me from installing DragonFlyBSD from a USB stick.

I first noticed the problem when trying to boot via USB using the 2011 Nov 17th "DragonFly-x86_64-LATEST-IMG.img".
I haven't tried older versions.

I can connect and use the USB mass storage device/stick after boot without problem, and shutdown while attached without problem.

################

I recompiled kernel with "options USB_DEBUG" and booted with verbose logging option.
The last lines shown are:

uhci1: <UHCI (generic) USB controller> [tentative] port 0x1860-0x187f irq 17 at device 26.1 on pci0
uhci1: Reserved 0x20 bytes for rid 0x20 type 4 at 0x1860
uhci1: LegSup = 0x0010
