Public bug reported:
used the live USB for Kubuntu and UbuntuStudio 23.10 as well as upgraded to
Mantic 6.5.0-10-generic from a Lunar 6.2.0-36 that works... all of the 6.5.0
64 bit kernel versions do a reboot loop prior to the splash screen display.
Processor is an AMD Ryzen 5600X, MSI MPG B550 GAMING PLUS Motherboard with 64
gig 3200 ddr4 ram. AMD Radeon RX6600 graphics...
latest BIOS firmware is installed, "fwupdmrg refresh --force && fwupdmrg
update" in root terminal reports no available updates.
in the advanced options of grub I can boot into mantic with the lunar
6.2.0-36 kernel. Cell phone video capture of the bad boot included...
Further testing found that a Mantic beta July 3rd build will boot (6.3
kernel)
booting to the current live Kubuntu USB with the 6.5.0-9 kernel and removing
hardware 1 piece at a time then replacing if the loop occurred found that as
soon as a VT6307 PCIe card is removed the 6.5.0-9 and 6.5.0-10 kernels will
boot properly. as soon as the card is reinstalled the panic reboot loop starts
up again... If there was a log generated from the loop I have been unable to
find one in the /var/log directory...
I have been unable to get kdump to work...
