I am changing the version to 'devel' to properly reflect that this recreates on
rawhide.
This probably shouldn't be in intltool's queue. A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you. changed:

I am going ahead to close this bug as 'fix_by_distro'. Pls re-open the bug if
the problem still appears on the latest FC. Thanks.

LTC Owner is: csiddali.com LTC Originator is: shaowu.com Problem description: We boot system leto.upt.austin.ibm.com from CD (boot.iso), then do network nfs install. Everything works normal until puting the nfs server ip and install directory. It hangs for a while (1 or 2 hours), and finally goes to xmon. another system medusalp1 does not have this kind of problem. Hardware Environment Machine type (p650, x235, SF2, etc.): 9113-550 Cpu type (Power4, Power5, IA-64, etc.): power5 Is this reproducible? Yes. If so, how long does it (did it) take to reproduce it? 30 minutes. Describe the steps: 1. reboot the system from fsp-leto, 2. go to SMS, then select IDE CD install, or network install for eth0 3. select NFS network isntall. Is the system (not just the application) hung? Yes. If so, describe how you determined this: it goes to xmon Is the system sitting in a debugger right now? Yes.
