https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293301 John Baldwin <jhb@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhb@FreeBSD.org --- Comment #4 from John Baldwin <jhb@FreeBSD.org> --- My guess is that the drm driver is using a Linux work item that gets mapped onto a taskqueue in its vd->vd_driver->vd_postswitch callback. Maybe something can be done to implement the emulation of work items to not use taskqueue, but a simpler fix for this case might be to teach the atkbd driver to defer the actual VT switch to a task instead of running it directly from the ithread? That last bit is probably simple to do at least. -- You are receiving this mail because: You are the assignee for the bug.home | help
