I have a HP DL360p G8 and I have updated all firwamres such as Bios, iLo and .. to the latest version but problem is when I open Virtual Console i can work with first connection and when I close that session and reopen it later I see this error:
and I can not work with virtual console in second time or future and I should reboot the server, any idea what is the problem? Thank you.
Hit Enter in the console window to awaken the cursor. This should be very easy to test.
Interrupt remapping does this on the G8 HP Servers (also on Debian, multiple reports on Proxmox forums) after kernel 5.4, making virtual console unusable. You can see this by booting a CentOS 7 LiveCD, which should work without any problems for long periods of time.
Try to disable remapping by pressing 'e' on grub to edit your kernel and adding 'intremap=off' or 'nointremap' at the end of your boot options. If that fixes your problem, add it permanently by using grubby, if not, try also setting intel_iommu off and booting with both options disabled, people have had success with that.
To complete schris's answer, RHEL (and derivatives RockyLinux, AlmaLinux) 8.4+ (with kernel 4.18.0-240+, according to https://bugs.centos.org/view.php?id=18223, integrating some 5.x iommu patches) are also affected.
Instead of completely disabling interrupt remapping at all, for me disabling interrupt remapping source-id checking with intremap=nosid was enough (documentation: https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html).
To make this change permanent, add this argument to GRUB_CMDLINE_LINUX in /etc/default/grub and regenerate the grub config grub2-mkconfig -o /boot/grub2/grub.cfg.
Also, some of the exchanges mentioned and resources I found:
Thoses links also mentions the following solutions (none working for me on RockyLinux 8.5 installer):
