Running Debian-sparc64 on qemu

I'm trying to install and run debian-sparc64 on qemu, but I'm having some
difficulties...

My command line for the installation is:

qemu-system-sparc64 -machine sun4u,usb=off -smp
1,sockets=1,cores=1,threads=1 -rtc base=utc -m 4096 -boot d -drive
file=debian_sparc64.qcow2,if=none,id=drive-ide0-0-1 -cdrom
debian-12.0.0-sparc64-NETINST-1.iso -device
ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-1,id=ide0-0-1 -msg timestamp=on
-serial mon:telnet::3333,server,wait -nographic -net nic,model=ne2k_pci
-net user -monitor stdio

I have created a 120Gb qcow2 drive image
When I select the disk to format, I get this warning:

The disk has 328965 cylinders, which is greater than the maximum of 65536.

And, during the installation, I get this error:

[ 1205.239608] watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
[dpkg-deb:11819]
[ 1229.239264] watchdog: BUG: soft lockup - CPU#0 stuck for 44s!
[dpkg-deb:118199]

what would be the best command line to be able to install and run
debian-sparc64 on qemu?
And, i'm using the last sparc64 release, from today ( 06/14/2023 )

Ps: I'm using Windows :/
