I downloaded kernel source from
extracted the drivers/scsi/aacraid/
and recompiled it with dkms this new module now see the card... it bugs, I guess 'cause I "force-compiled-it" (I had to add -Wno-incompatible-pointer-types and I had to comment out part of the source as

/var/lib/dkms/aacraid/1.2.2/build//linit.c:1480:14: error: initialization of ‘int (*)(struct scsi_device *, int, void *)’ from incompatible pointer type ‘int (*)(struct scsi_device *, unsigned int, void *)’ [-Werror=incompatible-pointer-types]
  .ioctl = aac_ioctl,
/var/lib/dkms/aacraid/1.2.2/build//linit.c:1480:14: note: (near initialization for ‘aac_driver_template.ioctl’)
/var/lib/dkms/aacraid/1.2.2/build//linit.c:1482:20: error: initialization of ‘int (*)(struct scsi_device *, int, void *)’ from incompatible pointer type ‘int (*)(struct scsi_device *, unsigned int, void *)’ [-Werror=incompatible-pointer-types]
  .compat_ioctl = aac_ioctl,
/var/lib/dkms/aacraid/1.2.2/build//linit.c:1482:20: note: (near initialization for ‘aac_driver_template.compat_ioctl’)
/var/lib/dkms/aacraid/1.2.2/build//linit.c: In function ‘aac_probe_one’:
/var/lib/dkms/aacraid/1.2.2/build//linit.c:1730:8: error: ‘struct Scsi_Host’ has no member named ‘max_segment_size’
   shost->max_segment_size = shost->max_sectors << 9;
/var/lib/dkms/aacraid/1.2.2/build//linit.c:1732:8: error: ‘struct Scsi_Host’ has no member named ‘max_segment_size’
   shost->max_segment_size = 65536;

so I just got it to compile to see if it will see the card, and it does... so there is def. something wrong with the aacraid module that comes with centos 8 ( 4.18.0-301.1.el8.x86_64 is running attm)

You can test the latest in-kernel driver by installing kernel-ml from ELRepo. I see:

filename: /usr/lib/modules/5.11.16-1.el8.elrepo.x86_64/kernel/drivers/scsi/aacraid/aacraid.ko.xz
version: 1.2.1[50983]-custom
license: GPL
description: Dell PERC2, 2/Si, 3/Si, 3/Di, Adaptec Advanced Raid Products, HP NetRAID-4M, IBM ServeRAID & ICP SCSI driver

@toracat don't I need kernel 5.11 to load them ?
never used this kernel-ml package, how to load the driver from /usr/lib/modules/5.11.16-1.el8.elrepo.x86_64/kernel/drivers/scsi/aacraid/aacraid.ko.xz instead a default location /lib/modules/4.18.0-301.1.el8.x86_64/kernel/drivers/scsi/aacraid/aacraid.ko.xz ?

installed kernel-ml from elrepo
new driver works (shows the same version but "modinfo aacraid" shows it's loading it from the 5.11.16-1 tree)

no clue how kernel/modprobe now decides what driver to load, will have to check that out (will appreciate link to some doc if you have one to share) but this works :) thanks

In the RHEL/CentOS kernel, many device IDs have been removed from the aacraid driver. Your device [9005:0285] must be one of them. This is why the driver in the upstream ( kernel works.

The best solution for you is to use ELRepo's kmod-aacraid package. There, the ones removed from the distro kernel have been added back. So please give it a try.

@toracat, yes, elrepo kmod works, thanks

That is great to hear. Now closing as 'resolved'. If you have any question regarding the kmod, you can go to ELRepo's venues (mailing list or bug tracker).
