		bzAuthorUnsubmitted Done Inline Actions This does not work; I kept running into panics with it and switched back locally to actually running it in a thread. Could do other ways than starting a thread as well but it seems we will need a deferred context. bz: This does not work; I kept running into panics with it and switched back locally to actually…
		hselaskyUnsubmitted Not Done Inline Actions I see. How will you disable the device interrupts during the execution of that worker thread? Right now while the linux_irq_handler() function is executing the device IRQ is masked. When this function returns the device IRQ is unmasked. Are you sure those panics can't be fixed? hselasky: I see. How will you disable the device interrupts during the execution of that worker thread?
