[Bug 41091] Re: Ubuntu crash when connecting to port replicator

I've just tested with the 2.6.24-15-generic kernel from Hardy, and I can
confirm the bug is still there. Lock up within a second of docking.

I've done some other tests, comparing Ubuntu's 2.6.22 kernel with one I
built myself: my kernel works, but the bug occurs if I use the .config
file from Ubuntu. The testing is a slow process, so I've not narrowed
down to the guilty configuration options. I've attached a diff between
the config files.

The initial obvious candidate for investigation is CONFIG_NO_HZ, but
booting the Ubuntu kernel with "nohz=off" on the command line didn't fix

** Attachment added: "Diff between Ubuntu config (fails) and my config (works) for 2.6.22"
