I can trigger the same problem by just typing setfont. For whatever reason, my other Fedora 21 computer only has this problem if I type setfont and not if I run systemd-vconcole-setup. > My uneducated guess is that your virtual machine boots up with a > non-graphical console, and the tool thus tries to upload the fonts > into the good old VGA hw text mode glyph tables, and qemu is very slow > at that... Or something like that. setfont is doing this: nanosleep({0, 250000000}, NULL) = 0 ioctl(3, PIO_FONT, 0xfbc010) = -1 EINVAL (Invalid argument) write(2, ".", 1.) = 1 nanosleep({0, 250000000}, NULL) = 0 ioctl(3, PIO_FONT, 0xfbc010) = -1 EINVAL (Invalid argument) write(2, ".", 1.) = 1 nanosleep({0, 250000000}, NULL) = 0 ioctl(3, PIO_FONT, 0xfbc010) = -1 EINVAL (Invalid argument) write(2, ".", 1.) = 1 nanosleep({0, 250000000}, NULL) = 0 ioctl(3, PIO_FONT, 0xfbc010) = -1 EINVAL (Invalid argument) write(2, ".", 1.) = 1 nanosleep({0, 250000000}, NULL) = 0 ioctl(3, PIO_FONT, 0xfbc010) = -1 EINVAL (Invalid argument) write(2, ".", 1.) = 1 This thing has only a serial console: # cat /proc/consoles ttyS0 -W- (EC a) 4:64 setfont does this: /* we allow ourselves to hang here for ca 5 seconds, xdm may be playing tricks on us. */ while ((loop++ < 20) && (i = ioctl(fd, PIO_FONT, buf))) { if (loop <= 1) fprintf(stderr, "putfont: PIO_FONT trying ...\n"); else fprintf(stderr, "."); usleep(250000); } fprintf(stderr, "\n"); Alexey, would it make sense to remove this loop or to add a way to turn it off? Thanks, Andy
