request_mem_region failing because of overlapping memory

lk flag

I understand that I am running the Tesla K80 not in its preferred environment, but I have seen regular consumers use this product successfully so I tried it myself.

I followed this, with an bit more up to date ubuntu version (Ubuntu 22.04.2 LTS) and the driver from here, but the graphics cards memory is unassigned

/sbin/lspci -d "10de:*" -v -xxx

I think this is claiming the memory

[    0.193803] pnp 00:00: disabling [mem 0xfed40000-0xfed44fff] because it overlaps 0000:03:00.0 BAR 1 [mem 0x00000000-0x3ffffffff 64bit pref]
[    0.193803] pnp 00:00: disabling [mem 0xfed40000-0xfed44fff disabled] because it overlaps 0000:04:00.0 BAR 1 [mem 0x00000000-0x3ffffffff 64bit pref]

A other synthome of this problem is that my tty2 get flooded with this these messages:

[  606.073710] NVRM: The NVIDIA probe routine failed for 2 device(s).
[  606.073711] NVRM: None of the NVIDIA devices were initialized.
[  606.073942] nvidia-nvlink: Unregistered the Nvlink Core, major device number 511
[  606.553951] nvidia-nvlink: Nvlink Core is being initialized, major device number 511

[  606.554683] nvidia: probe of 0000:03:00.0 failed with error -1

So the only other graphics drivers that were installed and not blacklisted(like the nouveau) where the intel i915, but blacklisting them, got me these errors

   16.326014] NVRM: GPU 0000:03:00.0: RmInitAdapter failed! (0x22:0xffff:667)
[   16.326053] NVRM: GPU 0000:03:00.0: rm_init_adapter failed, device minor number 0

[   16.562258] NVRM: GPU 0000:04:00.0: RmInitAdapter failed! (0x22:0xffff:667)

Since the Nvidia Tesla K80 does not have video output, I prefer having the integrated graphics card drivers installed.

Here a bit more information about my system

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
