AUR folks, This is a general question that may catch others off guard. Having patch for the 6.8 changes when the kernel was release and having no issues through 6.8.9-Arch1, I was very surprised to see build failures in the nvidia-utils 390.xx package after the today's update. For both Linux and Linux-LTS: ( 8/13) Install DKMS modules ==> dkms install --no-depmod nvidia/390.157 -k 6.6.30-2-lts Error! Bad return status for module build on kernel: 6.6.30-2-lts (x86_64) Consult /var/lib/dkms/nvidia/390.157/build/make.log for more information. ==> WARNING: `dkms install --no-depmod nvidia/390.157 -k 6.6.30-2-lts' exited 10 ==> dkms install --no-depmod vboxhost/6.1.50_non_OSE -k 6.6.30-2-lts ==> dkms install --no-depmod nvidia/390.157 -k 6.8.9-arch1-2 Error! Bad return status for module build on kernel: 6.8.9-arch1-2 (x86_64) Consult /var/lib/dkms/nvidia/390.157/build/make.log for more information. ==> WARNING: `dkms install --no-depmod nvidia/390.157 -k 6.8.9-arch1-2' exited 10 ==> dkms install --no-depmod vboxhost/6.1.50_non_OSE -k 6.8.9-arch1-2 ==> depmod 6.6.30-2-lts ==> depmod 6.8.9-arch1-2 The actual errors seem like regressions somewhere as similar bugs were fixed in the past 3-4 years for both Nvidia and Vbox. The errors are: In file included from /var/lib/dkms/nvidia/390.157/build/common/inc/conftest.h:5, from /var/lib/dkms/nvidia/390.157/build/common/inc/nv_stdarg.h:29, from /var/lib/dkms/nvidia/390.157/build/common/inc/os-interface.h:27, from /var/lib/dkms/nvidia/390.157/build/nvidia/nv-frontend.c:12: /var/lib/dkms/nvidia/390.157/build/conftest/functions.h:76:2: error: #error wait_on_bit_lock() conftest failed! 76 | #error wait_on_bit_lock() conftest failed! ... /var/lib/dkms/nvidia/390.157/build/common/inc/nv-linux.h: In function ‘nv_ioremap_nocache’: /var/lib/dkms/nvidia/390.157/build/common/inc/nv-linux.h:568:17: error: implicit declaration of function ‘ioremap_nocache’; did you mean ‘ioremap_cache’?

Anybody have a guess in what changed in either the new gcc or new util-linux or others that has cause all this fun? -- David C. Rankin, J.D.,P.E.
