For testing purposes I obtained the hidups executable from Fedora Core 3 and the same thing happened. That might indicate a problem with the USB or HID drivers rather than the hidups program. could you please try the new nut-2.0.2-1 from rawhide, it will be available in rawhide in next day. For testing you should probably boot the kernel from FC3, which worked before. Thanks I am already running nut-2.0.2-1 but I am unable to boot an FC3 kernel as I no longer have any systems with FC3 installed any more. I am still getting tons of errors in dmesg but I'm no longer experiencing the dramatic slowdown I was getting when I first installed FC4. yes, it seems a bug in USB or HID drivers. You could install the working kernel from FC3 on your FC4. Could you please try this? Thanks I installed and rebooted into 2.6.12-1.1372_FC3 I started upsd using nut-2.0.1-1 It seems to be working with no slowdowns but /var/log/messages contains a lot of the following: Jul 20 10:58:02 penguin hidups[3625]: Unhandled event: 0x840065 (0) Jul 20 10:58:02 penguin hidups[3625]: Unhandled event: 0x8500db (0) Jul 20 10:58:03 penguin hidups[3703]: Ignoring x86 page event 0xff860060 (8) Jul 20 10:58:03 penguin hidups[3703]: Unhandled event: 0x8500d1 (1) Jul 20 10:58:03 penguin hidups[3703]: Unhandled event: 0x850043 (0) Jul 20 10:58:03 penguin hidups[3703]: Unhandled event: 0x840073 (0) Jul 20 10:58:03 penguin hidups[3703]: Unhandled event: 0x85004b (0) Jul 20 10:58:03 penguin hidups[3703]: Unhandled event: 0x840065 (0) Jul 20 10:58:03 penguin hidups[3703]: Unhandled event: 0x8500db (0) Jul 20 10:58:06 penguin hidups[3625]: Ignoring x86 page event 0xff860060 (8) reassign it to kernel Pete, any ideas ? I'm way out of my depth with usb bits.. I'm not versed in details of hiddev either. Takes a lot of reading, it's a convoluted thing. I suppose I could diff something, then attempt to match the printed events against any new code. At least Greg told us to base on 2.6.12-1.1372_FC3, so that's something. Than is not off the hook completely though. These messages are printed by the userland and the act of printing eats cycles too. Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks. I still see this behavior in kernel-2.6.13-1.1526_FC4. I'm now running Linux penguin 2.6.13-1.1526_FC4 #1 Wed Sep 28 19:15:10 EDT 2005 i686 athlon i386 GNU/Linux No change from the previous 2.6.12 based kernel in that the errors are still present but there has been no noticeable system slowdown when using this USB UPS.

I suggest to just comment them out for now in an errata. it's fixed in 2.0.2-0.fc4.1, which will be pushed out this week. *** Bug 164051 has been marked as a duplicate of this bug. *** I'm running nut-2.0.2-0.fc4.2 and the problem seems to be fully resolved for me at least. |
