usb-uhci.c: interrupt, status 3, frame# 1876

This is a known problem, here is the discussion that I initiated on linux-usb-devel:

http://marc.theaimsgroup.com/?t=98609508500001&w=2&r=1

The right fix is to comment that printout out. In fact, that is what I commited for Red Hat 7.1 release.

Some people suggest to switch to uhci instead of usb-uhci, which helps precisely because it does not have a corresponding printk.

I'm not sure of that. Sometimes keys get "stuck" in the down position with my USB keyboard (mechanical switches, so the keys themselves are not sticking) and usually when that happens I can find a line like the one quoted above in the logs. Also, occasionally my mouse goes black (one of the optical Logitech's) with a similar line and must be disconnected and reconnected to work again. Again, similar line in the logs.

Nothing fatal happens. Pressing another key fixes the keyboard and my old fashioned USB ball mouse ;) works fine.

I've seen similar suggestions for people with AMD-based systems.

The printout is a valuable diagnostic tool for hacking but is useless for a user (actually dangerous, as it brings computers down with /var overflow). The best option would be to have it configurable with a module parameter.

That sounds like a good idea actually, under kernel hacking perhaps? It seems to me that the messages do indicate some kind of non-fatal problem (that may not be true?) but I agree it is murderous to /var on a small system. Given that I now consider a small system one with a /var of under 300 megs, well.. =)

Techical solutions are not a matter of voting. Two legislations in the US
states almost decided that the value of Pi be 3.14, exactly. Popular vote
does not make for a correct solution.
