The combination of a 2MB Cache P4 3.0GHZ CPU, and a Giga-byte GA-81848P775-G (Intel 848P chipset) motherboard produces this problem. Other simialar hardware may be affected. If you encounter this problem, see this bug report for a workaround.

*aic7xxx driver hangs on installation boot**
On some Compaq Proliant servers (specifically an ML370 G2), & possibly others, the aic7xxx driver will hang if there is nothing connected to the adaptor or if it is not terminated correctly. On most Proliants you can tell the BIOS to not allocate an IRQ to the device which effectively disables it; the ML370 G2 uses an AIC-7899 chip on the motherboard. This problem also exists in the ~CentOS 4.3 base. SME 6.0 loads fine which would seem to indicate that the newer driver in ~CentOS 4.3 can't handle the older system (this Proliant is probably 5 years old).

*older sistems stop at reboot
This problem is present on SME 6.0 servers. This may be an issue from the older P2 and early P3 era BIOS'es, that didn't follow the "specs" for power saving features. Also,this problem seems to be more prevalent in multi-CPU machines. Only a kernel change could provide a real fix to this issue.
For some motherboards, there may be a workaround by adding appropriate text to the grub config.
The addition of the noapic and acpi=off to etc/grub.conf might solve the problem of reboots failing.
