I apologize for the inconvenience you and your reporter facing, however I can not avoid to say that the problem appears to be specific to the AMD Ryzen machines. I've already received the similar report[1], and have been investigating it in the last few weeks, then got the insight. Please take a look at my short report about it in PR to Linus for 6.7-rc1: https://lore.kernel.org/lkml/20231105144852.GA165906@workstation.local/ I can confirm that I have been abe to reproduce the problem on AMD Ryzen machine. However, it's important to note that I have not observed the problem on the following systems: * Intel machine (Sandy Bridge and Skylake generations) * AMD machines predating Ryzen (Sempron 145) * Machines using different 1394 OHCI hardware from other vendors such as TI * VIA VT6307 connected directly to PCI slot (i.e. without the issued PCIe/PCI bridge) Currently, I have not been able to obtain any useful debug output from the Linux system or any hardware error reports when the system reboots. It seems that the system reboots spontaneously. My assumption at this point is that AMD Ryzen machines detect a specific hardware error triggered by Ryzen machine quirk related to the combination of the Asmedia ASM1083/1085 and VIA VT6306/6307/6308, leading to power reset. I genuinely appreciate your assistance in debugging this elusive hardware issue. If any workaround specific to AMD Ryzen machine quirk is required in PCI driver for 1394 OHCI hardware, I'm willing to apply it. However, it is preferable to figure out the reboot mechanism at first, I think.
