Blackbird / Re: RAM slot B1 not showing
« on: July 16, 2020, 08:46:30 am »
Oh. I forgot to mention: I had asked support about the memory I was intending to buy (Crucial) and they replied that it should work with the memory stick that came with the machine (Samsung).

Have you checked this link: ?


Blackbird / Re: RAM slot B1 not showing
« on: July 16, 2020, 12:10:13 am »

My Blackbird came with 16GB (Samsung) on the back slot (relative to the user seating in front of the computer). I've bought another 16GB from Crucial (CT16G4RFD8266 16Gb Ddr4-2666 Rdimm, 16 Gb (1 X 16 Gb), Ddr4 Sdram, 2666 Mhz Ddr4-2666/Pc4-21300, 1.20 V, Ecc, Registered, 288-Pin, Dimm) installed it and it worked for a few days.

Then it stopped worked and I've tried all combination front/rear slot samsung/crucial and found that both sticks work on the front slot but not on te rear slot, giving me only 16GB. Neither work on the back slot alone and I suspect the back slot is not working or there is some firmware issue that was triggered when I added the additional stick on the back slot.

I opened a support ticket on Raptor (my machine is brand new and came with a defective power supply, which took a month to be replaced). It seems your issue is similar to the one I'm experiencing.

Have you opened a ticket with Raptor?


Hi I have no idea of what dmsg is. How do I check it?


Thanks for the information, I found it where to clear the "compress" option.



Both are NVMe over PCI. I use Thunderbird because I work with gmail and I cannot stand it's web interface, just cannot find things at a glance like with Thunderbird.


Hi All,

I'm using this Black Bird for two weeks now. I've installed Fedora 32 with KDE/Plasma on this Power9 v2 machine with 32GB, 4 cores and plenty of disk.

When compacting the local mailboxes (Thunderbirds asks for it a few times a day) usually Thunderbird becomes unresponsive but I can use other applications. Today it froze the whole system for about a minute, I could not change application, it made remember Windows 3.1 with it's incipient multi-tasking capability.

My system barely gets over 40% memory util and vCPUs were supposed to work independently one from the others.

Any ideas of what might have happened? I wonder may be disk access. I have two disks: 128GB with boot and LVM for root/local. The second disk of 256GB I use a partition of 120GB as a LV which I added to LVM and used it full to extend /home. Both are PCI connected.

Maybe when compacting the mailboxes the access to the disk made by Thunderbird are so heavy to the point of not allowing the system anything?

Any inputs are appreciated.


Hi bw42 and Classic, thank you for your inputs.

It seems that it is beyond my knowledge to use QEMU user mode.

For now, I'll have to use my phone or another computer to access my bank and find an alternative to TeamViewer, something web based.


Thanks! Would you know what is the QEMU user command I would type to run TeamViewer I downloaded for Fedora on X86?

Again, thanks in advance.

I've tried using the QEMU user space but could not resolve dependencies.

I've succeeded installing Ubuntu desktop 20.04 but it is so slow that it is not practical.

One thing I noted is that no matter how many vCPUs I define it uses just one.

Any ideas on how to make QEMU use more than one vCPU?


Hi, this QEMU user space seems really interesting. I mean, using the host kernel is a smart way to improve (degrade less) the performance.

I read the articles and I'm not sure how it would work. This security module usually runs as a service which the browser uses to secure the connection.

If I understood it correctly, I would have to install the module every time I create the QEMU "session", install say Firefox and open it. Did I get it? I would have to create a script for this and once the "session" ends both the security module and the Firefox would disappear, just like in a sandbox.

Did I get correctly?



I need to install warsaw security module to access my bank account. This module works with most browsers but is a binary that runs only on X86.

Other than that, I'm fine with Fedora 32 on ppc.

Any input is much appreciated.


Hi All,

I need to run an X86 application and have not succeeded installing any Linux distro (I've given up on Windows). I've tried Linux Mint, Ubuntu 20.04 Desktop and Fedora 32 Desktop and all failed to install. I've tried with VM Manager and also QEMU command line.

Anyone succeeded? If yes, I would appreciate very much if you can share details on how to install it.

Anyway, up to now my experience with QEMU emulating X86 has been that it is VERY slow and, no matter what I configure, it uses only one vCPU.

Thanks in advance.

Hi ClassicHasClass,

Thanks for sharing the link. I was really excited but the installation of Win 10 failed with both 64/32 bits version. The installation proceeds until the last stage (about some 30 minutes) and fails with a message that there is a missing file/driver.

Any idea of how to fix this? when setting up the install I tried with E:\viostor\w10\amd64 (for the 64 bits version) and with E:\viostor\w10\x86 (32 bits).


Hi ClassicHasClass, thanks. I've checked the link you sent, it's way advanced for me.

Hi Guys, thank you all :)

So, it seems hardware virtualization is enabled. I created a Fedora 32 VM through virt-manager with 2 vCPUs and installed stress. When I stress the 2 vCPUs I see on the host System Monitor that 2 of my 16 threads are at 100% (thread 9 and some other thread, which keeps jumping among the other 15..). So, if I got it right, this VM is really having 2 vCPU fully allocated to it. If it did not have hardware virtualization enable would I still be able to allocate 2 threads?
