Possibly related is that there are 27 kernel modules in use by the old 
wheezy kernel :

Most of those exist for 6.12.3-sparc64-smp with a few missing.

The absent ones are :
     crc_t10dif.ko
     ehci_hcd.ko
     ext2.ko
     fscache.ko
     ohci_hcd.ko
     usb_common.ko

Not sure what else could be needed other than the ones that I
can locate :

     6.12.3-sparc64-smp/kernel/drivers/ata/ata_generic.ko
     6.12.3-sparc64-smp/kernel/net/sunrpc/auth_gss/auth_rpcgss.ko

A minimal initrd with just the above *should* be workable?
