Hey Guys, I'm relatively new to Arch linux (But not linux overall - I finally re-visted Arch after 7 years and finally understand enough to atleast get a working system lol).
Anyways, I'm running into an issue with the `lspci` command on my laptop. On my desktop, `lspci` returns almost instantaneously, and all is well. On my laptop, it takes like 2 minutes for lspci command to return after a fresh boot, and is faster for a while (though still not instant). While it still technically works after waiting, it's annoying to wait the 2 minutes for `hyprland` to wait for a return from lscpi to determine which graphics cards I am using.
I am on Kernel: 6.11.1-arch1-1
and nvidia drivers: nvidia 560.35.03-10
This is the output from `lspci` when it finally finishes.

this is from dmesg, and the same errors appear in journal.

UPDATE:
So, I did some sleuthing, and the PCI Bridge, as indicated by
[ 30.979983] pcieport 0000:00:1c.6: broken device, retraining non-functional downstream link at 2.5GT/shad a downstream device that was malfunctioning. being this device:
rtsx_pci 0000:2d:00.0:lspci -vvv2f:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev 01)
Subsystem: ASUSTeK Computer Inc. Device 202f
!!! Unknown header type 7f
Interrupt: pin ? routed to IRQ 128
IOMMU group: 21
Region 1: Memory at 84200000 (32-bit, non-prefetchable) [size=4K]
Kernel driver in use: rtsx_pci
Kernel modules: rtsx_pcishowed that the Realtek Card reader was Unassigned class, which from my searching, is normal for that type of device, but it seemed to be causing my issue, or that device is borked. Anyways, I went into the bios and went to
Security > I/O Interface Security > Card Reader Interfaceand set the value to
Lockwhich according to my bios disables the device. Now lspci works as intended and returns almost instantaneously. While I know this isn't a "full" solution as I'm effectively sacrificing part of my laptop, In all honesty, it's a Micro sd card reader, and I already have an external one(since I need it for my desktop) so I'm okay disabling that reader for my use, which is to have hyprland start normally (since it's checks GPU's on startup, which is how I noticed lspci was slow in the first place)

Woah thank you so much, I was just starting to look into this issue and I found this post which was pretty much reading my mind.
Same exact issue with same laptops, your solution worked fine.
Noone needs Micro USB anyways
