DOOM startup failure

[google0101-ryan]

I built the latest release from the git repository using clang on debian. It compiles without issue, but when I boot and run doom, it spits out the following message:

[pmm.c] memory stats: available: 127 MiB  
[pmm.c] unavailable: 449 KiB
[pmm.c] taken by modules: 11 MiB
[kernel.c] SnowflakeOS 0.7
[kernel.c] kernel is 214 KiB large
[ps2.c] initializing PS/2 devices
[ps2.c] keyboard
[ps2.c] mouse
[mouse.c] enabled scroll wheel
[mouse.c] five buttons enabled
[kernel.c] loaded module disk
[kernel.c] loaded module symbols
[paging.c] page fault caused by instruction at 00001029 from process 3:
[paging.c] the page at 0005fa48 wasn't present 
[paging.c] when a process tried to write to it
[paging.c] this process was in user mode

I have no idea what caused it. Also, I had to change the Makefile to create misc/root/etc and misc/root/mnt properly.

Hi! Thanks for the report. To be sure, are you using the commit tagged v0.7 (59ddb6f) or the latest master (d0d1eb1) ? What emulator are you running on ? I haven't been able to reproduce the crash or Makefile mischiefs yet but I'm very interested to.

I was running on qemu-system-x86_64, and I am using the default master branch that shows upon opening the page. The ISO I downloaded from the releases section (v0.7) worked fine. I am learning to develop operating systems, so the pre-compiled ISO is not of much use to me. Your operating system inspired me, and I would really like to see it functioning when built from source.

To clarify, I am building on an HP Chromebook 14 G5, using Linux (Beta). I experienced an issue in the makefile were misc/root/etc and misc/root/mnt were created as misc/root/{etc,mnt}. Everything except DOOM works as expected.

Thanks for the info! I'll fix the directory creation thing in a bit, it's due to the {a,b} thing being a bashism, and debian using dash for /bin/sh.

Could you maybe send me an ISO you built that crashes (along with the "isodir/modules/symbols.map" file) ?

[google0101-ryan]

Sure, as soon as I can. But it may be a while before I am able to. Thanks!
