Hi all,Since upgrading to the 2.6.21-rt series kernel I've seen that IRQ 23 is constantly using a small amount of the CPU. This is true in 2.6.21-rt9 (what's the '.3'?) and 2.6.21-rc5-r12.
.3 is just because Ingo's realtime-patch also ships the stable patch from kernel.org
Before I report this to the kernel mailing list I thought I'd ask here whether anyone else has seen anything like this? I haven't seen any discussions myself but I thought it didn't hurt to ask.
