| |
Hi Linus,
Please accept this request for v6.7 final. It includes a patch to suppress unexpected system reboot which I reported[1]. The issue affects all versions of Linux kernel which includes 1394 OHCI driver, so I expect to apply the patch to stable and longterm kernels as well as mainline, which includes 1394 OHCI driver.

firewire: ohci: suppress unexpected system reboot in AMD Ryzen machines and ASM108x/VT630x PCIe cards (2024-01-05 21:28:08 +0900)
---------------------------------------------------------------- firewire fixes for 6.7-final
This pull request includes a single patch to suppress unexpected system reboot in AMD Ryzen machines with PCIe card consisting of Asmedia ASM1083/1085 and VT6306/6307/6308. When 1394 OHCI driver for the card accesses to a specific register in PCI memory space, the system reboot often occurs. The issue affects all versions of Linux kernel as long as the 1394 OHCI driver is included. The mechanism of unexpected system reboot is not clear, so the driver is changed to avoid the access itself when detecting the combination of hardware.
