NetBSD dustpuppy.deadpixi.com 3.0_BETA NetBSD 3.0_BETA (DUSTPUPPY) #0: Wed Jul 13 10:40:32 CDT 2005  root@dustpuppy.deadpixi.com:/usr/src/sys/arch/amd64/compile/DUSTPUPPY amd64

>Description:
Whenever a device is plugged into a USB2.0 controller or one of its USB1 sub-controllers, the entire system locks up. When running with DEBUG_EHCI enabled, inserting and removing the device after the "lock up" reveals that the device is still responding (still get debugging messages about device insertion and removal), but the remainder of the system is completely unresponsive. This includes network connections.

This problem also exists in NetBSD-2.0.
>How-To-Repeat:
* Compile a kernel with EHCI enabled.
* Insert a USB device into a USB2 port, or boot with one attached.

 You need to provide more information, like the output of
 dmesg.  I have an amd64 machine that exhibits no problem
 with ehci, so this must be something machine specific.

 Maybe it's some interrupt problem?

 Have seen probably the same problem when installing on a Dell Optiplex GX 620
 (Intel 82801GB/GR EHCI controller).

 A amd64 build installed fine but the x86 build locked on the initial boot
 language selection screen. Building a distribution with ehci disabled
 sorted the problem.

 Cheers Steve.
