2022-05-25 Thread KIMATA Tetsuya
As a temporary measure, disabling IOMMU as follows seems to prevent the
error.

sudo vi /etc/default/grub
+ GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=off" 

sudo grub-update

[Kernel-packages] [Bug 1971505] Re: DMAR: ERROR: DMA PTE for vPFN 0x8e8fe already set

2022-05-04 Thread Mauricio Faria de Oliveira
Your attachments came through after I sent last comment.

You could get to a shell in order to run the commands?

CurrentDmesg.txt does show an interesting error (but
it starts in the middle of the flood) going to ext4/
scsi/ata/intel DMA, which is the DMAR handler/thing.

Having messages from before/when the error started
happened might be helpful still; if it's possible
to get them.

Thanks!

[Kernel-packages] [Bug 1971505] Re: DMAR: ERROR: DMA PTE for vPFN 0x8e8fe already set

2022-05-04 Thread Mauricio Faria de Oliveira
Hi Michael,

Thanks for reporting this bug.

We'd need some kernel messages to understand where it's coming from.

It looks like the Gen8 Microserver has iLO / serial console support.

Can you please check whether you can setup a serial console on it?
Then you might need linux kernel option 'console=ttyS1' (or ttyS0).

If that works and you get kernel boot output in it, you should be
able to record a boot by running 'script' then, it the shell that
it opens to record terminal history/activity, connect to the SOL
serial console over lan/network (e.g., SSH, iirc), wait for the
issue to be logged; then quit the console, and 'exit' the
script shell, and upload the recording/generated 'typescript' file.

Hope this helps,

Title:
  DMAR: ERROR: DMA PTE for vPFN 0x8e8fe already set

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I got this error after a fresh install of Ubuntu 22.4 
  The server is a Gen8 Microserver. I moved from Fedora 35 to Ubuntu. 
Everything was working before the format and reinstall. 

  Unfortunately, I cannot get to a command line in order to gather any other 
logs as the server is hung in mid boot with this error flooding the screen.
