https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229995 Warner Losh <imp@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |imp@FreeBSD.org --- Comment #5 from Warner Losh <imp@FreeBSD.org> --- To elaberate, loading the linuxkpi drivers from loader.conf causes the modu= les to load earlier in the boot sequence before interrupts are enabled, threads= are running and everything is fully initialized. There are dependencies in the = code on these things working, so when they aren't the system crashes. One of three things can make this better: (1) Make the code fail to load if loaded too early and print a warning (fail safe). (2) Fix the code to work early in boot or (3) Make the code do a deferred attach fo the drivers until after interrupts are running. 1 & 3 are likely easy, but would require some fussing around to get right. = 2 is likely quite hard and would take a fair amount of effort. Of the three, I'd recommend #3 for anybody looking at this bug. I'm not entirely sure that #3 would work, but reasonably sure. --=20 You are receiving this mail because: You are the assignee for the bug.=
