Bug Description
I noticed a strange behaviour when plugging in a USB device in Dapper. As soon as I plug in any device, system freezes completely beyond any recovery. Disabling hal everything works fine.
It should not a kernel-related bug because I was running the same kernel in Breezy without any problem.
More info can be found here: http://
Please find here attached lspci and /proc/cpuinfo output
If you need more info, please let me know.

It seems this bug is related to uhci_hdc kernel module. If you remove it using rmmod a crash doesn't occour.

When passing acpi=force option to the bootloader, everything goes right.
I tried this with the LiveCD. I'm going to test it on a hdd-installed version as soon as possible.

Thank you for your help, but I am not able to get a backtrace because system crashes as soon as an USB device is plugged in.
As you can see from bug #50610, this behaviour only occours when ACPI BIOS is disabled. I heard about a related kernel bug, but a Debian system installed on my PC running the same kernel and hal version is not affected at all.
