From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020607 Description of problem: When installing Red hat v7.2 on a Dell server with AACRAID/PERC SCSI controller using the Dell Server Assistant an aacraid_pciid option is placed in the modules.conf. This works fine with the default 2.4.7 kernel package installed by the RH CDs. If upgraded to kernel 2.4.9-31, RH v7.3 kernel 2.4.18-3 or kernel 2.4.18-4 then the aacraid driver fails which may also effect being able to mount the root file system. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Boot Dell Server Assistant CD and select to install Red hat v7.2 2.Install Red hat v7.2 with the root file system on an aacraid logical drive 3.Successfully boot the 2.4.7 kernel and login 4.Run rhn_register and up2date -f kernel 5.Reboot and watch the kernel panic about there being no / to mount 6.Power off 7.Boot Red hat v7.3 install CD and upgrade (Hey! Anaconda has new a slide show while it installs. So, when do I get to play Tetris like in that other distribution?) 8.Reboot and watch the kernel panic about there being no / to mount 9.Boot Red hat v7.3 CD and do "linux rescue" 10.Run chroot /mnt/sysimage (the mounted file system that booting from the hard disk couldn't find) 11.Run /etc/init.d/network start 12.Run up2date -f kernel 13.Run exit and exit 14.Reboot and watch the kernel panic about there being no / to mount 15.Boot Red hat v7.3 CD and do "linux rescue" 16.Run chroot /mnt/sysimage 17.Remove the aacraid_pciid from the /etc/modules.conf 18.mv /boot/initrd-2.4.18-4.img /boot/initrd-2.4.18-4.img-orig 19.mkinitrd /boot/initrd-2.4.18-4.img 2.4.18-4 20.exit and exit 21.The / is found, boot successfully! Actual Results: Kernel panics, hair loss and eventually a working work-around provided by "tatooin" on the Dell Customer Forum: Software - Linux. Expected Results: A pre-install or post-install script from the 2.4.9 and/or 2.4.18 kernel RPM packages should have stripped aacraid_pciid from the /etc/modules.conf allowing for a reboot without kernel and user panics. Or if not a kernel RPM script then at least Anaconda should have engolfed the offending modules.conf line. Additional info: Tetris is fun. Kernel panics are not. :-)
