All ia64 machines we have available for testing continue to work, no system support was lost during this cycle. No, we even got another "system" back: the HP Sim platform - up to mainline, that is. Together with Ski [2], thankfully kept together and updated by Sergei Trofimovich, this allows to run ia64 kernels and (light) ia64 userland software on for example x86_64 hosts. Like it's done for the recently established auto-builds for Linux stable RCs and releases on GitHub. Have a look on [3] for example: all building, all working (in Ski). For the manual testing of the Linux mainline RCs and releases some changes were introduced. Mainly that compilation always happens with the latest gcc-14 snapshot starting with v6.8-rc1 - so far no surprises - and recently, the enabling of LRA for the compiler.

We collected the following examples for this regression (if they are all related): * Debian: apt(-get) segfaults (though not immediately) and is affected to a different degree depending on non-usrmerged or usrmerged root FS * Gentoo: segfaults happen when emerging different packages * T2: compiling a specific Perl source code file with gcc leads it to segfault ...and hope to find the cause of it and a solution. Before you ask, no, this is not due to enabling LRA for the compiler, it already happened before that was done. **** This time no new distributions for ia64, but unfortunately one less soon: Debian will close shop on ia64 ([4]). As much as this make me sad, because this was the distribution that got me going on ia64 nearly ten years ago, better switch to another option sooner than later. I am switching to T2 ([5]) for example for future testing. For network boot this was really simple to set up, similar to how you can create an OpenBSD root FS by unpacking a list of tarballs plus some manual configuration afterwards.
