Instead of defering every input of a USB console keyboard to a timeout via a queue of one element, only differ entering ddb(4) once a matching control sequenece has been typed. This prevent loosing inputs when a USB console keyboard is "too fast". Fix a problem reported by matthieu@, Adam McDougall and Hrvoje Popovski. ok stsp@, dlg@

Re: DDB causing lost keystrokes on Dell iDRAC console (not inside ddb)
Looks like this never got a response and we are seeing the same issue. OpenBSD 6.0, Dell 330, iDRAC 8, trying to get a console with the iDRAC. Works great with Linux or ESXi on the box, but OpenBSD does not work. There is major keystroke loss which makes it impossible to use. Is there a way to disable DDB without recompiling?

DDB causing lost keystrokes on Dell iDRAC console (not inside ddb)
Hello, I have a few Dell servers which I've installed OpenBSD for testing but ran into a problem with keystroke loss on the console when used through the Dell iDRAC remote graphical console. Surprisingly it operates perfectly fine in the installer (thankfully) but when booted from a formal install, I lose 25-50% of my keystrokes. The speed that I type does not matter, the keys I type do not matter, they are randomly lost. This is any typing, for example at the login prompt (where it becomes very difficult to login). Example: login: Tisis metypingat he onole should have shown: This is me typing at the console I was able to determine having "option DDB" in the kernel is a single factor leading to keystroke loss. If I recompile the GENERIC amd64 5.8 kernel without DDB, I have no keystroke loss. Also, if I enter DDB while the kernel is running, I have no keystroke loss. I have noticed this issue on 5.8 release, a recent 5.9 snapshot, and at least the Dell models R420 and R430. The iDRAC supplies a virtual usb keyboard to the OS. I have not had this issue with other OSes. I should generally be able to perform further tests as requested especially this weekend. Does anyone have suggestions? Can I disable DDB without recompiling? Thanks.
