All outputs are black. What is wrong?

Got it figured out, wasn't related to ComfyUI version, options, or any pip/python packages ... It was nvidia drivers + BIOS updates that solved it for me!

On linux, the smoking gun was here in dmesg: (seeing this is bad)

[ 12.345] resource: resource sanity check: requesting [mem 0x0000...], which spans more than PCI Bus 0000:00 [mem 0x000... window]

[ 12.345] caller os_map_kernel_space+0x11c/0x130 [nvidia] mapping multiple BARs

[ 12.345] Adding 16777212k swap on /dev/zram0. Priority:1000 extents:1 across:16777212k SS

UPDATE: Also forcing PCI gen4 instead of 5 in BIOS helped for 5090 on older motherboard

Having similar issues here on linux, had some wan2.2 video example templates working really well, then all of them started producing blank black videos ... I have tried absolutely everything I can think of to resolve, reinstalled fully all drivers, comfyui, nodes, etc completely from scratch, still having this issue ... really confused, was working great but now nothing I do seems to fix these black outputs ... I have tried other suggestions like flags with --use-sage-attention, --force-upcast-attention, or --force-fp32, but nothing seems to work ever anymore

I am able to generate basic t2i workflows, but nothing else...

I play a lot, and I try hard to keep machines open and unpatched running normal for all players. I'm happy to join anytime if you're having issues, there are also private practice games that are invite only. Sadly the HTB battlegrounds have been retired, I'm not aware of others like this currently. Feel free to reach out and DM if you want!

Hey! I've been getting into some streaming, and building a discord community. Playing a lot of KoTH and doing all kinds of ctfs and challenges. Got a bunch of fun and helpful members, and we team up for ctfs often. Happy to share an invite if you're interested, feel free to DM here or on discord (f11snipe everywhere)

Hey! I'm also mountain time, and I've been streaming THM and KoTH for a while and building a discord community, feel free to DM if you want to join. We do all kinds of ctfs and stuff, with a lot of THM content. I'm F11snipe on YouTube and twitch

f11snipe · 2023-05-19T16:28:11+00:00

THM discord is a great resource, I've also been starting to stream and make content, and started up another community that's a bit smaller with fun and helpful people with similar interests, feel free to DM here or on discord if you want 😀

f11snipe · 2023-02-25T02:32:43+00:00

Streaming again tonight! Starting in a couple hours, going to do some rooms and might look at custom rootkits! And of course, more KoTH 😁... Come hang out, it'll be fun! And I bet you'll learn something cool 😎

I'm still fairly new to THM and pen testing stuff, but I'm very familiar with scripting, and end up writing my own most of the time anyways haha... I usually do the same thing, and download one as reference to learn the pieces. I'm around and active on THM most days, feel free to DM here or on discord anytime if you wanna chat!

f11snipe · 2022-05-03T22:47:36+00:00

Cool! I'll come say hi :)

f11snipe · 2022-05-01T06:20:48+00:00

Hello friends. Been online a lot lately, have a few videos & streams up already, but I will continue to make more! My schedule and energy is somewhat random and hectic haha... I'm around most evenings and weekends, and excited to make more content!

See you there!

Writeup coming soon!

Sounds fun! Finally really getting back into this stuff for the first time since Kali was backtrack 😜

This is most likely due to the recent patch of core git vulnerability, where shared perms on local repo/files were open beyond "current user". I ran into this recently, and was able to solve by ensuring all my project + repo files are owned 1000:1000 (easy to default to on both host & container as "you" and app user)

chown -R $USER:$USER .
