Bug has disappeared with kernel-2.6.11-1.14_FC3 update |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: After kernel update to 2.4.10-1.741_FC3 kudzu hangs the machine on system startup. Only cold boot helps. After chkconfig --del kudzu it now hangs on cups startup. Version-Release number of selected component (if applicable): kernel 2.4.10-1.741_FC3 How reproducible: Always Steps to Reproduce: 1. Update kernel up to 2.4.10-1.741_FC3 2. reboot machine with kudzu enabled Actual Results: Machine hangs Additional info: I have added strace to the rc.d/kudzu script and strace output shows that kudzu hangs in read() from /proc/bus/usb/devices With the previous kernels (up to kernel-2.6.9-1.724_FC3) I had no problems on my machine. The only external usb device I have is D-Link Bluetooth DBT-120 dongle. I have tried to remove the dongle when kudzu "sleepls" in read(). It helps (!) and strace shows that kudzu returns from the call and machine boots fine afterwards. It also boots without dongle. If I plug in the dongle after the system startup and then run service kudzu start it doesn't hang. Very strange but 100% reproducable on my machine. Looks like some ehci/ohci modules loading and /proc reading race in the latest kernel Btw, the motherboard is Gigagbyte K8NNXP, nForce3 chip, amd64
