Dear all, After the last kernel update (2.6.15-1.1831_FC4) the rt2500 (RaLink WiFi) driver is causing the system to freeze on modprobe -- on restarting the PC the boot process hangs and hence renders the machine unusable. A post on the rt2x00 driver forum led me to the information that SMP is enabled even on single processor FC kernels (at least from 2.6.15 on). I just though it must be a mistake and dutifully filed a BUG report: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=182640 But, within minutes of posting the report, I got a reply that the it is NOTABUG & CLOSED! The reason provided was "The performance loss from running SMP on a UP x86_64 machine is negligable." Now, what I don't understand is what good is SMP on a UP kernel?? If I want SMP, I'll install the SMP kernel. I assume I'm not the only one who needs to run a UP kernel to make certain hardware work that won't otherwise work with SMP! Someone please tell me why anyone would want SMP enabled on UP kernels? If this is the way it's going to be then I'll have no other choice than to recompile every new kernel that is released... and I really hope it doesn't come to that... Your comments please. -M
