argulp argulp Posted July 29 Share Posted July 29 Hello Each time I try to upgrade to kernel 6.6.39 on a rockpi-4a the system become unbootable: ## Flattened Device Tree blob at 01f00000 Booting using the fdt blob at 0x1f00000 Loading Ramdisk to f01f6000, end f1f0Ad94 ... OK Loading Device Tree tn 00000000f0179000, end 0000 000f01f5fff ... OK Starting kernel ... efi_free_pool: illegal free 0x00000000f0f0d04 efi_free_pool: hllegal free 0x00000000f0f0a040 I have another rockpi-4a but with a rockpi4b image (installed by mistake) I was able to copy the file 6.6.32 from this system to my other one (creating the older symlink on /boot) , and I have be able to boot card successfully so I have try to upgrade this other rockpi-4a (running a rockpi-4b image) and upgrade has been a success. So I have trying again on the first rockpi... and error appear again, it's related only to kernel image of 4a or the related dtb file It's not urgent, because I can revert the install, if you need something let me know Thanks for your jobs !!! 0 Quote Link to comment Share on other sites More sharing options...

argulp argulp Posted July 30 Author Share Posted July 30 Hello, after some troubleshooting, this boot issue occur only if I have my two ssd drive plugged. If I unplug this one, the kernel is booting, this issue is not occuring with older kernel 6.6.32 By the way, since the system is booted, if I plug the drives, the system panic so I will revert to 6.6.32 kernel. but I have loose my 6.6.32 headers, and I can't compil again the zfs module, anyone know how i can download the last 6.6.32 headers for rockpi ?
