Here's a quick overview of my system:
AMD Ryzen 5 1600
MSI B450 Tomahawk w/ latest BIOS
16GB DDR4 3200 G.Skill TridentZ
Silicon Power 256GB - NVMe M.2
Nvidia Quadro NVS 295
LSI 9211-8i HBA with Intel RES2SV240 expander
3x 10TB Western Digital
Seasonic Prime 650 Titanium SSR-650TR
I started installation via a thumb drive with the network install image. During the installation process it was not able to detect my onboard NIC. Doing some research I determined that it was a resource conflict. I removed the LSI HBA card and everything seemed to work properly. Putting the card back in, it would not work at all and I would get the following error:
Code: Select all
mpt2sas_cm0: unable to map adapter memory!
So it appeared that my HBA card was working properly, I was able to use the three 10TB drives that were attached to it without any apparent problem. Upon looking at dmesg however, I have noticed the following problem:
Code: Select all
[ 0.101877] pci 0000:25:00.0: BAR 9: no space for [mem size 0x00400000 64bit]
[ 0.101879] pci 0000:25:00.0: BAR 9: failed to assign [mem size 0x00400000 64bit]
[ 0.101880] pci 0000:25:00.0: BAR 7: no space for [mem size 0x00040000 64bit]
[ 0.101881] pci 0000:25:00.0: BAR 7: failed to assign [mem size 0x00040000 64bit]
Any idea on what the problem is? It seems odd that these errors appear, but I haven't noticed any adverse effects when using the drives through the HBA card. Thank you.

I was consistently getting many errors similar to this (didn't save the exact message):
Code: Select all
[ 120.101877] AMD-Vi: Event logged [IO_PAGE_FAULT device= .....................]
I also had a stability problem under no load and the system was reporting soft/hard lockups. The PC wouldn't run longer than 24 hours without something like the following happening and forcing my to hard reset manually:
