No, it is not a known issue. Which task(s) did you install?
Note that you do not need to install GNU/Hurd to build GNU Mach, just
git clone git.savannah.gnu.org:/srv/git/hurd/gnumach.git
and autoreconf -i && ./configure && make. If you have a 64bit box, you need to
cross-compile:
CPP='gcc -m32 -E -x c -undef -ansi' CC='gcc -m32' LD='ld -melf_i386'
./configure --host=i686-unknown-linux-gnu
Thinking again about, IIRC the kernel will just boot fine, it's only in some
application use case that the issue shows up. I'll attach a patch which shows
the CR0 value before and after Mach changes it. The 0x20 flag currently shows
up both before and after. It should only show up after (because Mach sets it).
To easily get the boot logs, pass console=com0 as kernel parameter during the
multiboot command, that will direct logs to the serial port.
