[CentOS-virt] missing bnx2x firmware files in Xen4CentOS CentOS6 kernel 3.18.12-11
Hi folks As mentioned in the subject, kernel-3.18.12-11 is missing firmware files required to run Broadcom/Qlogic network cards, driven by bnx2x driver. While in the source-rpm, there is a bnx2/bnx2x firmware tgz being applied during the rpm build, along with a patch adding these firmware files to firmware/Makefile, neither the tgz nor the patch contain the required firmware files. In 3.18, the driver bumped to version 1.710.51-0, requiring the following firmware files/versions to work: firmware: bnx2x/bnx2x-e2-7.10.51.0.fw firmware: bnx2x/bnx2x-e1h-7.10.51.0.fw firmware: bnx2x/bnx2x-e1-7.10.51.0.fw I helped myself by either copying the required firmware-files to the target-machines' /lib/firmware/bnx2x dir and ultimately by adding the files to the source-rpm along with a new Makefile patch and rebuilding the kernel rpms. However, as bnx2x NICs seem quite commonplace these days, I suggest to fix this 'upstream'. If required, I can provide the (trivial) patch. I pulled the firmware-files from a CentOS 7 stock kernel.

[CentOS] 7.1 install with Areca arc-1224
I must be doing something horribly wrong and I hope somebody can help. The Areca arc-1224 is not supported by the Areca driver included driver in 7.1 so I have to supply that when starting the install. Documentation provided by Areca and in the Red Hat install guide say the same thing, put the driver on an accessible medium then append inst.dd on the boot command, choose the driver and now the drives show up. So far so good. There's already a possible glitch, however. The USB memory stick is mounted as sda1, shifting the hard drives off by one letter. So I break into the shell and partition the drives the way I want them, go back to the GUI installer and select the drives I want to use, assign mount points and formatting options. Done with that, configure the network and disable kdump. Start the installation. Give it a root password. Install completes, reboot. Only it won't boot. Boot the DVD again, use troubleshooting with rescue option, again providing the new Areca driver. Tell it to mount my install under /mnt/sysimage. Look around a bit, there's almost nothing I expect to see in /boot, there's no kernel image. Do chroot /mnt/sysimage and query the RPM database, I see kernel-devel, kernel-headers and kernel-tools-libs. Hmmm, I'll bet that's a problem. What the heck?? I actually did try copying the kernel and a few other required RPMs into a directory inside the chroot jail, install them and that worked fine, so I know those bits on the DVD are good. Someone please tell me what I did to screw this thing up so badly. Linus ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
