Red Hat Bugzilla – Bug 185229
Unable to install on AMD64 with MPT SCSI controller and > 2GB memory
Last modified: 2013-08-05 21:18:33 EDT
Description of problem:
System Config follows:
- Abit KN8-SLI board
- AMD X2 dual-core Athlon 64 4600+
- LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)
I've installed RHEL 4 U2 on this system when it only had 2GB on it. No problems
at all. Upgraded to 4GB memory and first I got an error about "high address but
no iommu." Got around that by passing iommu=soft to the kernel.
Next problem is that the SCSI controller kernel module seems to fail with an
error "mptbase: Initiating ioc0 recovery" over and over.
Booting with only 2GB of memory seems to make it work just fine.
Version-Release number of selected component (if applicable):
I am using the RHEL 4 U2 boot.iso image burned to CD to do an installation.
Boot with > 2GB memory on the above hardware configuration.
Steps to Reproduce:
1. Boot with > 2GB memory on the above hardware configuration.
"mptbase: Initiating ioc0 recovery" over and over.
Sorry, I did dome more experiments and it seems that up to but not including 4GB
of memory works. It is when the system tries to address 4GB or more.
I did a boot with mem=4000M and it seems to have cleared the problem up. If I
boot with mem=4096 I see the issue again.
This is a real pain since booting with mem=4000 results in only 3469036 kB
memory recognized (cat /proc/meminfo).
Additional info - the same issue is present with FC5 on this system. If I don't
choke memory by using mem=4000M at boot time the system doesn't boot.
Can you get a serial console capture of a failed boot session and attach it to
I will go get a null-modem cable now, and will have serial console set up in an
hour or two. Back soon with details.
Well, never mind. This is a KN8-SLI motherboard. No serial ports at all. Just
Try booting with 4000M, then do a sysreport and attach the result.

sysreport from FC5 box with mem=3490M
This is FC5. I will reload with RHEL 4 U3 and upload that sysreport in a
Created attachment 127981 [details]
RHEL 4 AS U3 x86_64 SysReport
RHEL 4 AS U3 x86_64 SysReport
FYI - I bought a USB to serial adapter and null modem cable, but passing
console=ttyUSB0,9600 to the kernel at boot time did not work. The USB adapter
only worked after the system was up and had populated /dev. Sorry.
I encounter the same situation when I want to install RHEL4U3 into IBM e325 server
This server have 4G mem two AMD 248 CPU and LSI 53c1030 PCI-X Fusion-MPT Dual
Ultra320 SCSI Card
I use IBM e325 server with 4G mem and LSI 53c1030 PCI-X Fusion-MPT Dual
Ultra320 SCSI Card.
I use two SCSI disks config as RAID1 in 53c1030
After some test I found the mem=2000M did't make my e325 installation startup
with same error.
I found if I recompile the kernel linux-2.6.9-34.0.1 whith out PCI_MSI option
the kernel will startup successful.

latest update. Please try the most recent RHEL4 kernel and verify that this is
