[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 did a few more restarts. Sometimes it hangs after the cpu_pause i.e. outputs "AK: just after cpu_pause. ticks_left 1161010" with a gray cursor at the bottom left corner of the screen.

And sometimes it hangs in the middle of showing the output from "kprintf("AK: just after cpu_pause. ticks_left: %d\n", ticks_left)"
i.e. it outputs "AK: just after cpu_p"  with a gray cursor at the end.

cdrom eject button works fine when in this hung state.

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
