kernel can't be built witn CONFIG_IR_ITE_CIR set to 'm' (due to missing mdelay function). See koji logs: http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=196250 http://ppc.koji.fedoraproject.org/koji/getfile?taskID=196255&name=build.log
This is a bug in the driver.
Fix queued for upstream (simply add include of delay.h), and added to 2.6.38.4-20.fc15 and later. (Nothing actually building yet, but it'll be present in the next build, whenever someone gets around to doing it).
kernel-2.6.38.4-20.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/kernel-2.6.38.4-20.fc15
kernel-2.6.38.4-20.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report.
It seems to work now - thanks!
