Well, a Google search shows that microcodes 0x100098 and 0x100009f are not that rare. IMHO, it is a pretty safe bet that both Debian and Ubuntu have some users of those microcodes. Users who will have their systems rendered unbootable (until we teach them about the dis_ucode_ldr parameter to the kernel) if they ever install the amd64-microcode package in a kernel that doesn't have this patchset. So, it is really a bit of both: I had several "it doesn't work" type of reports for both AMD and Intel over the years, and most often people won't come back to the initial bug report, if they even go that far as to report a bug in the first place: they just remove the microcode update packages and disapear... so, I wouldn't know if any were due to this specific issue except by luck. But I do assume there are at least 20 users having trouble that will never report it for each single bug report I get, and it is likely to be a lot more :-( -- "One disk to rule them all, One disk to find them.
