https://bugzilla.kernel.org/show_bug.cgi?id=220341 --- Comment #6 from Nicolas BARANGER (nicolas.baranger@xxxxxx) --- Hi all Unfortunatly I don't have this laptop anymore (dell xps 15 9530), but from my remember of last summer issue, rmmod -f followed by insmod don't work as rmmod -f was not able to remove the module from the kernel. The only way I found to recover the situation was to forcely reboot the system . Also, don't know if it's related but I remmember that I had no issues during the last 2 weeks I used this laptop (corporate laptop) and that was just after removing pcie gen5x2 nvme m2 drive end replacing it by a mdadm done with 2 pcie gen4x4 nvme drive. Also note that the issue always happens when I was using an Aquantia AQC100S 10gb nic plugged on thunderbolt bus and maybe when cpu total load was higher to 30% on pcie bus My feeling was an hardware issue at I/O or DMA that kernel don't handle properly NB: I was using grub and not systemd-boot -- You may reply to this email to add a comment.
