I think this question is more suited for LKML. > While trying to find what these hickups come from I ran watch --interval > .1 "cat /proc/interrupts".

You should probably show the exact contents of /proc/interrupts and provide some details about the systems (architecture, CPU speed, contents of /proc/sched_debug, lspci output, dmesg output). > When b43 reappears in the interrupt listing, that line generates some > 25000 irq's within a fraction of a second. Is this a bug somewhere or by > design? It's possible that the interrupt count is not shown when the driver "disappears", but is not reset to 0.

That's probably a good idea, as the LKML folks would suspect something they know least about, i.e. the hardware. -- Regards, Pavel Roskin _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
