This sounds familiar. ISTR messages like this when I tried to use any PCIe cards in my machine, and the machine would typically lock up as soon as the driver for the PCIe card was loaded.

I eventually gave up on running with any PCIe cards.

What was interesting that the CentOS kernel package would run fine, but as soon as I rebuilt a mainline kernel with the same config and 4KB memory pages, the machine would become allergic to any PCIe card I put in it (tried several AMD and Nvidia GPUs and several SATA controllers).

Do you have any PCIe cards in yours?

Hmm, interesting. Perhaps if I can figure out how to get the kernel

booting

to actually display via video (or IPMI) then it would reveal an error message. It has never shown output after GRUB but I imagine there's a way

to

route it.

I was able to get output by adding this to my kernel parameters:

console=ttyS0,115200 earlycon=uart8250,mmio32,0x1c020000

From there, booting into 4.11, it hung here:

[ 4.168868] acpi ACPI0007:07: CPPC data invalid or not present [ 4.175198] GHES: HEST is not enabled! [ 4.179167] ACPI GTDT: [Firmware Bug]: failed to get the Watchdog base address. [ 4.187021] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled

From there, I added 'acpi=off' to the kernel parameters. Now I can

successfully boot the 4.11 kernel.

However, the console is flooded with messages like this:

[ 42.982471] pcieport 0002:00:00.0: TLP Header: 60001004 000000ff 00000090 30032000 [ 42.990201] pcieport 0002:00:00.0: AER: Device recovery failed [ 43.156938] pcieport 0002:00:00.0: AER: Multiple Uncorrected (Non-Fatal) error received: id=0000 [ 43.165695] pcieport 0002:00:00.0: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, id=0000(Requester ID) [ 43.177385] pcieport 0002:00:00.0: device [10e8:e004] error status/mask=00100000/00000000 [ 43.185695] pcieport 0002:00:00.0: [20] Unsupported Request (First)

I'm happy I can boot now. If I can also stop the errors, that'd be great. _______________________________________________ Arm-dev mailing list Arm-dev@centos.org https://lists.centos.org/mailman/listinfo/arm-dev
