Update: this is strangely related to nouveau
On a machine with a "NVIDIA MCP89 [GeForce 320M]" the nvidia drivers have been removed from 22.04. nouveau when run normally now causes a hang [see other reports if curious]
The described "firewire_ohci quits when using firefox" happens when kernel launched with kernel flag
nomodeset
When launched, instead, with
nouveau.noaccel=1
...normal usage does not affect firewire_ohci, as expected and desired
