Hi
I am astounded that the release notes for SL 7.2 do not contain a couple of known bugs I had previously reported before Christmas (with ZERO response on this list):

1. Masses of "kernel: AMD-Vi: Event logged [IO_PAGE_FAULT device=00:13.0 domain=0x0008 address=0x0000000000000080 flags=0x0020]" errors appearing after a few hours running.
It would appear the new kernel has picked up the IOMMU error reported in RH bugzilla 1274527. Running with amd-iommu = off stopped the errors, but is not a valid option for me.

2. For some AMD processors the kernel panics for all versions of kernel-3.10.0-327 up to 4.5 See RH bugzilla 1265283 and 1285235 This is surely a show stopper for some people, unless you install SL 7.1 and then upgrade to 7.2 only to find you have the IOMMU bug!!!

Is anything going to be done about these bugs?

Cheers
Bill Maidment
