Thank you for answer! Is this possible to configure system such that fbcon
works normally,
VTs work normally (i. e. via framebuffer), but when panic happens, it is
displayed via drm_panic? This seems to
be solution to the problem.
Yes, that's the default if you use a drm driver like bochs with fbdev
emulation enabled. (Of course you can't have DRM panic on a pure fbdev
driver).
There was a concurrency problem between fbcon and DRM panic, and I've
solved it a year ago with:
https://patchwork.freedesktop.org/series/136182/
So make sure you have the following in your .config:
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_DRM_PANIC=y
CONFIG_DRM_PANIC_SCREEN="kmsg"
