Following up on this, I found the following two bugs on RHEL. The first reports the same issues, and the solution of rmmod and modprobe aic94xx works for me. Ie, if I 'sudo rmmod aic94xx' and then 'sudo modprobe aic94xx', I can then mount my drives without issue, but I have to do this after each reboot.
The second bug points to a simple code change in hotplug.c, which seems to address another issue. According to the first bug, the patch provided in the second link fixes this problem in RHEL4/5. hotplug.c is responsible for loading the firmware through initramfs. https://bugzilla.redhat.com/show_bug.cgi?id=240105 https://bugzilla.redhat.com/show_bug.cgi?id=378651 I will investigate the code, but my environment is a non-build environment, so I cannot compile and apply the patch myself. :-( In my particular case, I don't need the drives on the aic94xx interface until after the machine boots, so I'm inclined to build a init.d script and put it at level 99, or something. ** Bug watch added: Red Hat Bugzilla #240105 https://bugzilla.redhat.com/show_bug.cgi?id=240105 ** Bug watch added: Red Hat Bugzilla #378651 https://bugzilla.redhat.com/show_bug.cgi?id=378651 -- bug with adaptec aic94xx raid https://bugs.launchpad.net/bugs/315763 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
