No luck with any PCIe adapter on Centos 7.2
- SIIG SATA crashes Tianocore when I connect it to a hard drive
I haven't tried a Marvell based add-in card myself as I don't have one lying around, but I have tried Silicon Image 3132 SATA and 3ware 9650SE SAS. They both crash only when I load the kernel driver, they all made it past the Tianocore UEFI boot (chain-loaded from u-boot - are you booting directly into Tianocore?)
It is worth noting that I managed to get it to not crash when using the CentOS supplied 4.2.0 kernel, but with a mainline 4.4.6 it panics the kernel due to, IIRC, an unaligned access error. Here is the kernel I used:
http://ftp.redsleeve.org/pub/misc/aarch64/kernel-4.4.6-1.el7.nosrc.rpm
There is 4.4.8 in the same folder, but I haven't tried that with PCIe cards yet as the machine moved from my test bench into production.
- Radeon 290X caused kernel panic on boot when using Marcin's
xorg.conf and kernel patch. I tried compiling the radeon driver as module and as built-in, but that made no difference http://pastebin.com/be4ucvfk 3) nVidia GT70 is not recognized by X even when using Marcin xorg.conf
- kernel patch.Compiling nouveau driver as module or built-in made no
difference. Both X -configure and startx returned an error every time I tried http://pastebin.com/q5ANbtp5 http://pastebin.com/XigAJ6zk
Does the kernel nouveau driver load?
In all 3 cases lspci recognized the PCIe adapter http://pastebin.com/EYAErr57
Given that we are seeing kernel panics with different SATA, SAS, AMD and Nvidia cards, the only thing I can conclude is that there is a major bug somewhere in the PCIe driver. The main difference between my kernel 4.4.x kernels and the CentOS 4.2.0 is that the latter uses 64KB memory pages, so that is probably a good place to start looking.
