Description of problem: kernel-smp-2.6.17-1.2174_FC5 fail to boot on HP nx9420. kernel-smp-2.6.17-1.2157_FC5 and other where OK. It looks like kernel is unable to find the root partition. I initially followed other bugs thread (see bug 189708) but was said it might be a different bug. Version-Release number of selected component (if applicable): kernel-smp-2.6.17-1.2174_FC5 mkinitrd-5.0.32-2 and previous parted-1.7.1-15.fc5 and previous How reproducible: Always Steps to Reproduce: 1.boot 2. 3. Actual results: Kernel try to find root partition and panic. Expected results: Additional info:
The problem could be SATA related. I tried to disable in my bios Native SATA and in this case, kernel-smp-2.6.17-1.2157_FC5 also fail. I suspect that something changed in last kernel related to SATA. lspci say: 00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA Storage Controllers cc=AHCI (rev 01) dmesg in attachment.

kernel-smp-2.6.17-1.2187_FC5 has still the same problem. But this link http://www.redhat.com/archives/rhl-list/2006-August/msg01840.html seems to be the response to my problem. Here is my modprobe.conf after I disabled multi lun support: #### alias scsi_hostadapter ahci #options scsi_mod max_scsi_luns alias eth0 tg3 install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; sleep 0.5 ; /sbin/ipw3945d --quiet remove ipw3945 /sbin/ipw3945d --kill ; /sbin/modprobe -r --ignore-remove ipw3945 #### After mkinitrd: mkinitrd /boot/initrd-2.6.17-1.2187_FC5smp.img 2.6.17-1.2187_FC5smp It now boot correctly !!
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.
kernel-smp-2.6.18-1.2200.fc5 is booting OK, including with this line in modprobe .conf: options scsi_mod max_scsi_luns=16 kernel-smp-2.6.18-1.2239.fc5 is not booting: it does not find the SATA disk.
max_scsi_luns=16 shouldn't be needed (we probe all luns by default). are you using raid by any chance ?
Actually kernel-smp-2.6.18-1.2239.fc5 was not booting at all, with or without the max_scsi_luns option. kernel-smp-2.6.17-1.2157_FC5 was booting ok with or without the option, kernel-smp-2.6.17-1.2174_FC5 was not booting with the option (but I do not know without) kernel-smp-2.6.17-1.2187_FC5 was booting without the option only, kernel-smp-2.6.18-1.2200.fc5 was booting ok with or without the option, kernel-smp-2.6.18-1.2239.fc5 was not booting at all but I did only some limited tests and do not remember if I did mkinitrd after chanding the option... Was this needed? I originaly added this option in an attempt to make the integrated SD card reader working... without success... Currently I upgraded to fc6... I can't test anymore... fc6 is working.
very strange. Ok, I'll close this.
