Hello, yesterday I compiled and booted 2.4.5-ac24 and got several 'invalid operand' messages in the syslog. I have attached two, decoded with klogd. I have only seen these with -ac24, -ac22 was fine (skipped ac23), and I have yet to see them with 2.4.6-ac1. I am not sure what would cause these errors, but I do know they appear in -ac24 only, relatively quickly. Hope this helps, kind regards, Roel Teuwen
