next in thread | raw e-mail | index | archive | help
Hello all,
I am encountering the following message on my root window:
Jun 6 14:18:53 ast kernel: stray irq7
Jun 6 14:43:42 ast kernel: stray irq7
Jun 6 18:18:47 ast kernel: stray irq7
Jun 6 19:29:47 ast kernel: stray irq7
I have noticed these stray irq messages periodically, but cannot isolate
what is causing them (the only mention of irq7 in dmesg relates to my
printer (parallel printer port)). In the past, they popped up quickly
prompting the message that there were too many stray irq7 and that it
wouldn't log them anymore (I forget the exact wording). This appears to
be a new problem (it hasn't happened that I know of since one of the
last 2 times I have re-built world (I tend to update thrice every two
months)). In case it is needed, I am running CUPS and have the
appropriate (or so I've been told) options in my make.conf file (see it
below). Does anyone have any ideas? I did some searching and came up
with nada. Below I show my uname as well as dmesg and make.conf. Any
help would be greatly appreciated. Thanks.
