https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229995 Warner Losh <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #5 from Warner Losh <[email protected]> --- To elaberate, loading the linuxkpi drivers from loader.conf causes the modules 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. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-x11 To unsubscribe, send any mail to "[email protected]"
