Thanks for the replies.

I would like mention a couple of things before I move into providing the gore
details.

First, I have moved from SuSE to BLFS.

Secondly, the problem seemingly disappeared since the introduction of kernel
series 2.16.19 as I don't remember of having seen those messages since then !

To the contrary, I once installed gentoo (just for the fun of it) which, used
2.6.21 (if I remember it right) and encountered similar messages. I am sure it
was again about too many requests for irq 11 but, don't remember if it was from
the serial driver itself !

Could it be possible that irq handling code changed somewhere in series 2.6.19
which possibly prevented the problem to some extent and the realtime patch
prevents it even further so, I don't get to see those messages at all !? But,
one thing for sure, I haven't seen those messages on my BLFS system since
2.6.19 which was without the realtime patch. I started applying realtime patch
since 2.6.21.

The machine I'm using is a laptop  and the BIOS on this machine does not
provide any options to (re)assign/change irqs at all. I would love to disable
some of the devices on this machine which I haven't used till this day. These
include firewire, card reader, PCMCIA slot, synaptics touchpad (which takes an
irq all for itself !!) but, there simply is no way I can do it, unless I hack
the BIOS ROM (I haven't the slightest clue how !?).

I've attached output from dmesg, lspci and acpidump.

Thanks again.

Kevin
