[Xen-users] 4.13.0-rc1 swiotlb buffer is full

[Andrew <andrew@xxxxxxxxxxx>]

Hi All,

I am trying to test xen 4.13.0-rc1

Dom0 boots, however it is crippled (networking doesn't work, can't 
reboot, etc)
dmesg of the host dom0 gives hundreds of lines like this:


ixgbe 0000:22:00.0: swiotlb buffer is full (sz: 8192 bytes)

ahci 0000:00:11.0: swiotlb buffer is full

ehci-pci 0000:00:13.2: swiotlb buffer is full

They start at boot.


This is a 4.19.76 kernel that otherwise runs xen 4.12.1 without issues.

I have a tried 5.3.5 kernel as well, the problem is there still ( 
according to 
https://wiki.xenproject.org/wiki/Xen_4.13_RC_test_instructions > 4.18 
kernel should be okay, but thought best to try against 5.x as well)

Any suggestions/advice appreciated.


Thank you,

Andrew.
