Have you seen any error messages in the kernel panic?
/dev/root: cannot open blockdev
vfs: cannot open root device "sdc4" or unknow-block (0,0): error -6
How many hard disks/SSDs are installed in your X1000?
3
Are they connected to the SATA ports?
yes
Is one connected to the IDE port?
no There is a catweasel on the ide port
Maybe you need to add "
rootdelay=5" to the boot arguments.
Dont work and rootdelay=10 dont work
Only "bootargs" or "setenv bootargs"?
setenv bootargs
Void PPC and Debian Sid PPC64 boot with the RC5 on my X1000.
On my x1000 there booting with 5.11 with no errrors . some of the 6.4 kernel work but not all

exactly this error I had if I tested PCIe x8 -> 2x PCIe x4 switch.
That was strange, because I not changed harddisk configuration, only config change was this:
linux gfx card HD6xxx was removed from 2.slot x8, into this slot I put PCIe switch and graphic card connect to one connector of switch.
I have some photos of screen. I stoped with switch testing due to little importance and very few time. But if Musa has the same error ( with different configuration ), it should be investigated. I hope I will do it on weekend.
P.S. are there debug version of kernel? Or are there some kernel command line parameters debug to serial?
Will work for us some of these?

Peter,
Thanks a lot for your answers. Currently, I don't have any ideas to solve the issues with your X1000.
I always test every new kernel very intensiv with Void PPC and Debian Sid PPC64 on my X1000.
Test steps:
- Boot with the vmlinux image from the internal CF card (including reboot)
- Boot with the zImage from the internal CF card (including reboot)
- Check CPU usage and network traffic
- Hardware check (HardInfo, lscpu, dmesg etc)
- Check hardware 3D acceleration (SuperTuxKart, Pangea games, videos with ViewTube etc)
- Test QEMU with KVM PR
- Test web browsing
- Check sound with the SB600 HD audio and with Bluetooth
- Access to other volumes (Hard disk, SSD, floppy disk, internal CF card, DVD drive etc)
- New: Check temperatures via the SMBus/I2C connected sensors (Thanks to sailorMH)
Sometimes, I boot with a LABEL. Maybe this is a solution for you.
You can also try to load the kernels from the internal CF card.
Cheers,
Christian

Hi Christian
I have tried booting 6.4_rc5 several times with no success.
I'm thinking about whether it's possible that the kernel package gets corrupted during download?
I have downloaded the file several times and sometimes I get this error when unpacking. ( gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now)
I was wondering if you could just pack in a different way one time , for example as a zip. Just to test that it is not my extracted file that is the problem.
Regards, Peter

Hi Christian.
i have tried downloading 6.4_rc5 on another computer (my pi4) and extracted kernel vmlinix-6.4_rc5 there. Then copied it onto my USB drive.
This time debian 64 boot on vmlinux-6.4_rc5. I think it is quite certain that my problems with some 6.4 kernels is due to corrupting during download on my main computer with ubuntu 22.4. I dont now why.
Have a nice day

Hi Peter,
Good to know and thanks a lot for testing!

Thanks, it works!
Byt I have to increase rootdelay to 10. Attempt with 5 ends with:
"Kernel panic - not syncing: VFS: Unable to mount rootfsom unknown-block (8,21)"

Have you booted the Linux userland from a USB stick/drive?

yes, I booted it classic way, no initrd, no label something like:
Code: Select all
setenv bootargs "root=/dev/sdbx rootdelay=10"
boot -elf -noints -fs=ext2 usbdisk0:vmlinux
In past I had problems with cfcard, both with fat and ext2. It is very often unreadable from CFE. Maybe I have to exchange my old cfcard.
