Hello, one of our servers crashes regularly, apparently during heavy network load. The log files are then full of this message:

Does somebody has any idea ? GRUB_CMDLINE_LINUX_DEFAULT="iommu=soft" is sometimes recommended in similar cases with IO_PAGE_FAULT. Maybe I should lower the speed from 10 Gbit/s to 1 Gbit/s as a test?
