Hi,

I got the Thinkpad T60 dock and the serial-to-usb cable. The issue is
that we found booting Thinkpad T60 with rumpdisk failed, so I collected
the log for navigation. I followed this link[0] to set up the
environment for rumpdisk. If I miss any neccessary information, please
remind me.

I set up three environments. (1) uses hd0 (i.e. old linux driver to
bootup). (2) and (3) use wd0 (i.e. rumpdisk). (2) uses SATA BIOS setup
AHCI. (3) uses SATA BIOS setup Compactibility.

In all three environments:
gnumach version: 20250304
hurd version: 20250420-1

Boot without rumpdisk:

- Setup:
BIOS Config:
SATA: Compactibility

In /boot/grub/grub.cfg:
multiboot /boot/gnumach-1.8-486.gz root=part:2:device:hd0 console=com0

In /etc/fstab:
/dev/hd0s2      /               ext2    defaults        0       1
/dev/hd0s1      none            swap    sw              0       0
/dev/hd2        /media/cdrom0   iso9660 noauto          0       0

Result: Success

My guess:
I guess is that there are some data races between acpi and rumpdisk. We
can see that the output started being messy after boundry of acpi and rumpdisk.
