Correction: Initializing Hardware network storage audio *HANG* A little inconsisant as I have now had this happen even with the rhgb option in the kernel params. In this case I had to change run levels in kernel params to get around the hang.
If you add -x to the #!/bin/bash line of /etc/rc.sysinit, where does it hang?
That's a good idea, here is the output: for module in '$other' load-module uhci-hcd LC_ALL=C fgrep -xq uhci-hcd /etc/hotplug/blacklist modprobe uhci-hcd This obviously tranlates into the following part of rc.sysinit: load_module () { LC_ALL=C fgrep -xq "$1" /etc/hotplug/blacklist 2>/dev/null || modprobe $1 >/dev/null 2>&1 } So it seems that this is kernel related and not initscripts related. I have tried removing USB devices one-by-one and it hasn't made a difference. My motherboard is an Aopen AX4C Max-II (Intel 875P & ICH5R chipsets). This has only started happening since the 136X kernel builds. I am unsure of how widespread this affect could be. How do you want to proceed with this?
Assigning to kernel for now.
Seems to have have something to do with load the USB kernel modules. If I hold down the shift key on my USB keyboard while these modules are loading, It will always successfully load the module and continue booting. If I do not hold down the shift key, there is a 50/50 change that it will hang at that point. I have installed the Rawhide 2.6.12 kernel and it *SEEMS* that this problem has gone away.
Mass update of -test bugs to update version to fc4. (Please retest on final release, and report results if you have not already done so). Thanks.
[This comment has been added as a mass update for all FC4 kernel bugs. If you have migrated this bug from an FC3 bug today, ignore this comment.] Please retest your problem with todays 2.6.12-1.1398_FC4 update. If your problem involved being unable to boot, or some hardware not being detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE* installing any kernel updates. If in doubt, you can recreate this file using.. mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak mv /etc/modprobe.conf /etc/modprobe.conf.bak kudzu Thank you.
I have not changed that config files but I have installed the new kernel as directed. The problem no longer exists. I will leave for you to close if you are happy to do so.
