Kernel Panic and system freezes with 4x16 DDR5

seth · 2026-06-03 21:46:06

I ran mkinitcpio -P before rebooting

cat /proc/cmdline

will tell you whether the parameters were applied - did you get a panic report for the latest occurrence as well? Or the system journal for the boot?

froze at 90min uptime yet again

Is there any pattern (time or usage-wise) to this? Is there a temperature limit?
W/ the page fault were're oc still in the realm of unstable RAM.

Yes, here is the output of cat /proc/cmdline :

initrd=\amd-ucode.img initrd=\initramfs-linux-zen.img root=UUID=f5fdea1a-3851-4c32-a944-c84705967219 rw rtw89_pci.disable_aspm_l1=Y rtw89_pci.disable_aspm_l1ss=Y rtw89_core.disable_ps_mod=Y pcie_aspm=off

Oddly enough, even when idling a game this time (to facilitate GPU usage) I did not receive a kernel panic. The system journal still does not show the moments of the crash (freezes so even SysReq is unusable).

The only concrete pattern I notice is that it occurs around 90min uptime (with at most that i have seen at about 92min). Temperatures are cool and I get the same numbers as I have gotten since I had this computer.

An additional note is that I idled overnight on a windows install and no freezing or BSODs occured.

Since I have tried the live ISO of Cachyos and it froze the same way, could it be an obscure issue with arch/based distros?

It's more likely an issue w/ more recent kernels => https://aur.archlinux.org/packages?O=0&K=linux-lts

Have I pointed you towards the 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Leaking RAM/GART/GTT?
Can you keep the system running longer when frequently (every 30m or so) isolating the multi-user.target (implies killing your GUI session and all GUI clients!) and in doubt reclaim memory, https://unix.stackexchange.com/question … ree-memory (using heads and tails should do )

That is intersting. As far as I am aware, AM5 is very temperamental about 4 sticks of ram so I try to avoid it.

I ran another 9+ hour memtest overnight and received over 19,000 fails on a memory address. This occurred heavily around the 90 minute mark(s).

Although I should've done it sooner, I am in the process of RMAing all 4 of my ram modules.

I will update as soon as I can test the new DIMMs

Here are the memtest results:

DIMM is 66°C at this point?
Can you do something to physically keep the system cooler (open it and blow a room fan at it)?
