Bit of an update - I installed RaspiOS to a SSD via USB adapter and got same issue with loss of external disk.
Quite a few input/output errors before system slowly becomes unresponsive.
Likey not to be an issue with Gentoo - rather the use of SSDs with the RPi5

carfentanyl,

If you don't overclock, is the problem solved?
Raspberry Pi OS is not Pi5 optimised. Its one 64 bit user space image for the Pi3/4/5.
Gentoo will be optimised which will make everything work harder, so overclocking is riskier.

Thanks for replying so quickly.
After your suggestion I tried the stock latest RaspPi OS on the RPi5 with my SSD via a USB adapter and got the same issues without overclocking. I wonder is some issue related to SSD power saving?

carfentanyl,
See Powering Raspberry Pi 5. The Pi5 is the first Pi that needs a PSU/Cable that can do the USB-C PD standard.
If that not used, power to peripherals is restricted to 600mA.
A SSD may struggle on just 600mA.
As the page says, there is a | Code: | | usb_max_current_enable=1 |
knob in config.txt that defeats that power limit. However, that will only move the power problem elsewhere.
A powered hub may help too. - Not to power the Pi, just the USB HDD.

thanks again Neddy, I had not come across that update on the Pi site.
I'm using the new 25W PS, and the USB hub has a 4A supply, it all works with the 3 SSDs and my Pi4 with gentoo.
Interestingly when trying to use vcgencmd on my gentoo setup the Pi5 gives a VCHI initialization failure, as I was trying to read usb_max_current (/opt/vc/bin/vcgencmd) |

|

I fixed what appeared to be a power supply issue with a switch in drivers from the UAS driver to the usb-storage driver
As its needed to load the root filesystem it has to be added to the cmdline.txt
usb-storage.quirks=aaaa:bbbb:u
a= idVendor b= idProduct (dont forget the :u) you can place a comma and list further drives if needed
In my case I got these from lsusb -t
The Realtek Semiconductor RTL 9210 USB3 to NVMe SSD adaptor used to work great with my RPi4 but not I have to force the inferior driver use with the RPi5. I don't think it will affect performance that much as you never really saturate SSD performance with either drive.
So for me cmdline.txt;
usb-storage.quirks=0bda:9210:u |

carfentanyl,
If that turns off UAS support, you only have 'bulk mode'.
That's like PIO mode on old IDE HDD.
For a speed test, try it on the Pi4 with both modes.

For those of you compiling/building on your Pi 5, what form of cooling are you using?
Active? My concern is noise.
Passive? Is there a solution that stays cool enough to not throttle?
Opinions? |

flysideways,
The official active cooler. The fan never goes above its lowest speed and its still silent. The hottest I've seen the CPU is 62 deg C.
Its not in a case and I'm still building on an SD card.
I have the geekworm armour case too. That's passive. It worked well on the Pi4.
I need to find some down time for the swap, or get another Pi5. I found a UK source.

Thanks, Neddy.
I had to order the official cooler and power supply. None to be found in stock locally. I didn't really expect to find the Pi 5 so soon, but I got lucky.
A long time ago I had people that would have milled a copper copy of one of the passive aluminum cases for me if I asked, but they're long gone. That would've been '83 to '89.
I really want passive like my Pi 4's, but, that can wait. |

| It seems I might have found a new hobby, a nearby library has a makerspace with a desktop CNC mill appropriate to the task. |

Cooling thoughts, I was concerned about the Factory active cooler, but they got it right. Late at night, when all is quiet, yes I hear it. During the day, with any ambient background noise, it blends in. Then there is the reality that it rarely is needed to run full out.
The passive cooler seems OK too, but I'll keep the Factory active cooler for the Gentoo Pi. |

flysideways,
The Geekworm passive cooler hit 85C and thermal trotting here.
The fix is to take an original Pentium passive cooler and jam its fins into the case fins :)

| Finally got RPi5 hardware. I've been running Gentoo on a RPi4b with kernel 6.7.1. I'm happy to say that I successfully moved my SDCard from the 4b into the new 5 and it started up without a problem! I just had to make sure I had the RPi5 firmware files in place. Wifi, ethernet, and BT all seem to work. I have an SSD and an SSD Hat coming in a couple days. Looking forward to seeing if I can get that to work and hopefully see a good speed increase on I/O. It's awesome that the transition seems to be pretty easy. |

I got one of the Geekworm passive coolers, it was next day Amazon here, go figure. It seems fine running RPiOS as a desktop. I am quite impressed with the Pi 5 in that application. It works for all of my normal browsing, far better than a 4.
I'm going to stick with the RPi active cooler for building and updating Gentoo. |
