Linux on Dell systems FAQ-O-Matic: After upgrading RHL 7.2 to kernel 2.4.9-{21,31,34} or to RHL 7.3 or later, I get a kernel panic when the aacraid driver loads

Adaptec-based PERC Controllers and ROMB :
After upgrading RHL 7.2 to kernel 2.4.9-{21,31,34} or to RHL 7.3 or later, I get a kernel panic when the aacraid driver loads

When you installed Red Hat Linux 7.2, you passed the PCI IDs of the on-board RAID controller to the aacraid driver. Your /etc/modules.conf file contains:
options aacraid aacraid_pciid=......
This option is no longer necessary in kernels 2.4.9-{21,31,34}, any Red Hat Linux 7.3 kernels, or later kernels, and its presence causes the driver load to fail. You may simply remove that line from /etc/modules.conf, remake your initial ramdisk with 'mkinitrd', and reboot.

The mkinitrd command will look something like:
/sbin/mkinitrd -v -f /boot/initrd-2.4.9-34smp.img 2.4.9-34smp
(with appropriate changes for your kernel version)

(A request to fix insmod to not fail under these circumstances has been filed and accepted with Keith Owens, modutils maintainer, and is pending for the 2.4.15 modutils release.)

Which controllers use the Adaptec aacraid driver?
