I've noticed RX packet drops on my PCI card (InDroppedDma was too high). I suspected that it was because of a firmware problem, so I decided to try to find a way to update it.
There was no official linux firmware updater, however I found an unofficial one published some time ago, which worked well when combined with the latest firmware.
Use at your own risk, however I didn't experience any problems.
hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:
If you've spent some time online, you’ve probably come across Zendesk.
Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like support@company.com), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.
Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

| #!/bin/bash | |
| # Steps: | |
| # 1) Make sure bash is available | |
| # 2) Create udev rule | |
| # - path to new udev rule: /etc/udev/rules.d/50-x-resize.rules | |
| # - udev rule content: | |
| # ACTION=="change",KERNEL=="card0", SUBSYSTEM=="drm", RUN+="/usr/local/bin/x-resize" | |
| # 3) Create /var/log/autores directory | |
| # 4) Create script /usr/local/bin/x-resize (this file) and make executable | |
| # 5) Reload udev rules with `sudo udevadm control --reload-rules` |
