Hi all,
I have a fresh install of Fedora 9 on a Dell poweredge 2650. Install went fine, no errors or warnings. Rebooted it, and it hangs after:
serial 00:06: unable to assign resources Red Hat nash version 6.0.52 starting INFO: task modprobe:<number here that I cannot remember> blocked for more than 120 seconds "echo 0> /proc/sys/kernel/hung_task_timeout_secs" disables this message. INFO: task scsi_scan_0:449 blocked for more than 120 seconds "echo 0> /proc/sys/kernel/hung_task_timeout_secs" disables this message.
We used 32bit fedora 9 to install onto a 3 dish scsi raid5. I am not sure if this machine is 32bit or 64bit, but I figured 32bit fedora should work on both?
Rebooted again, and now it's not doing anything. It gave the error about the serial, then started nash up, but now nothing. And it's been a half hour.
I am completely clueless right about now and any help would be greatly appreciated, even a point in the right direction :)

---- I have CentOS 5 (previously 4) running on a PE 2650 which came with a PERC 3/Di RAID adaptor (Adaptec actually) and it clearly is a 32 bit system so I would think that you installed the right version.
Obviously the installer ran and that tells you that the 32 bit OS works.
I would suspect that have a grub issue with the install (i.e. - not installing grub on /dev/sda)
Suggest that you do...
boot installation disk again enter 'linux rescue' at boot have it locate the installation for you and get to a command prompt type 'chroot /mnt/sysimage' type 'grub-install /dev/sda' type 'exit' type 'exit' remove the installation CD and reboot

---- come to think of it...did you add hard drives to the system after the installation that is confusing things?

It got stuck trying to scan a scsi device - perhaps the RAID array. If you hit a key during the boot prompt from grub and edit the boot line to remove the "quiet" it will spew rather more info which should help see what broke and where

Yes, and 64bit will print an error on 32bit.

You are right :) Tons and tons of this:
aac_srb: aac_fib_send failed with status: 8195
I found this https://bugzilla.redhat.com/show_bug.cgi?id=450444
Adding aacraid.dacmode=0 did not help, same errors. But mem=4G did. I went into the GRUB menu and edited the boot line ('e') and it booted fine.
Can anyone point me in the direction of how I would permanently fix this? I noticed on http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=... that it says "limiting the discovered kernel memory (mem=4G) with an associated loss in runtime performance" - is there a better way to fix this issue, now that I can actually access the box?
Thanks in advance!!! :) Much appreciated.
---- You probably realize this but you could add the mem=4G line to /boot/grub/grub.conf to permanently use that option.
You could also try using the PAE kernel as that is capable of addressing
3 GB of RAM
You probably want to make sure the firmware on the PERC 3/Di is the latest version as suggested by Jeff Lawson since he reported that the problem went away after updating (and using the PAE kernel but he was using CentOS 5, not Fedora)
