IRQ10 problem never seen in 9.0

Since FTPing into 9.1 I am suddenly seeing kernel messages like the following that never appeared in the several months I used 9.0 Pro: Oct 28 13:52:42 linux kernel: serial8250: too much work for irq10 Oct 28 13:52:43 linux last message repeated 327 times Oct 28 13:53:31 linux last message repeated 117 times I read (on this list, I think) that kernel 2.6.x handled IRQs better than 2.4.x. Seems this is not necessarily true --wherever I read it. The logs don't indicate where the problem lies, either, so I can only make a wild guess unless someone else has the answer. I hope the latter is the case. -- "Yogi" CH Namast� Yoga Studio
