Sun Fire V215 - No Graphics Card / Framebuffer - Genkernel 4.1.12 sparc64 Last few lines of boot process... [ 63.002062] Console: colour dummy device 80x25 [ 63.055381] console [tty0] enabled [ 63.096186] bootconsole [earlyprom0] disabled Gentoo still boots although we lose the console. I can SSH into the box after a minute or two. The install CD boots fine and copying the kernel config from the CD to /etc/kernels (in order for genkernel to use it) will result in a perfectly fine booting system. Notice this section from the kernel config from the CD... # # Non-8250 serial port support # CONFIG_SERIAL_SUNCORE=y CONFIG_SERIAL_SUNZILOG=y CONFIG_SERIAL_SUNZILOG_CONSOLE=y CONFIG_SERIAL_SUNSU=y CONFIG_SERIAL_SUNSU_CONSOLE=y CONFIG_SERIAL_SUNSAB=y CONFIG_SERIAL_SUNSAB_CONSOLE=y CONFIG_SERIAL_SUNHV=y CONFIG_SERIAL_CORE=y CONFIG_SERIAL_CORE_CONSOLE=y These Sun serial drivers are not set when using genkernel # # Non-8250 serial port support # # CONFIG_SERIAL_KGDB_NMI is not set CONFIG_SERIAL_SUNCORE=y # CONFIG_SERIAL_SUNZILOG is not set # CONFIG_SERIAL_SUNSU is not set # CONFIG_SERIAL_SUNSAB is not set # CONFIG_SERIAL_SUNHV is not set CONFIG_SERIAL_CORE=y CONFIG_SERIAL_CORE_CONSOLE=y I am building now with these options enabled, if that proves to be the issue then these options should probably be added to genkernel, otherwise Sun boxes without a framebuffer (most of them) may experience this issue if their serial console driver is not covered under CONFIG_SERIAL_SUNCORE.
I can verify that adding the following... CONFIG_SERIAL_SUNZILOG=y CONFIG_SERIAL_SUNZILOG_CONSOLE=y CONFIG_SERIAL_SUNSU=y CONFIG_SERIAL_SUNSU_CONSOLE=y CONFIG_SERIAL_SUNSAB=y CONFIG_SERIAL_SUNSAB_CONSOLE=y CONFIG_SERIAL_SUNHV=y to the genkernel config fixes the boot issue.
the generated kconfig turns out to be unusable on sparc anyway; I have tweaked the Git logic to use the older manual sparc config. Git commit 7eb2709 and cae778e10e
