I have seen these errors myself on some hardware. https://lists.debian.org/debian-hurd/2024/03/msg00037.html The ide drivers on the gnumach work on that Toshiba netbook. On other hardware I have been able to make rumpdisk work fine. This is the output of hwinfo --storage-ctl (running from linux) of a HP laptop where it works 01: None 00.0: 0102 Floppy disk controller [Created at floppy.112] Unique ID: rdCR.3wRL2_g4d2B Hardware Class: storage Model: "Floppy disk controller" Config Status: cfg=new, avail=yes, need=no, active=unknown 12: PCI 1f.1: 0101 IDE interface (ISA Compatibility mode controller, supports both channels switched to PCI native mode, supports bus mastering) [Created at pci.386] Unique ID: 3p2J.NMKmj2azXu3 SysFS ID: /devices/pci0000:00/0000:00:1f.1 SysFS BusID: 0000:00:1f.1 Hardware Class: storage Model: "Hewlett-Packard Company NX6110/NC6120" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x266f "82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller" SubVendor: pci 0x103c "Hewlett-Packard Company" SubDevice: pci 0x099c "NX6110/NC6120" Revision: 0x03 Driver: "ata_piix" Driver Modules: "ata_piix" I/O Ports: 0x1f0-0x1f7 (rw) I/O Port: 0x3f6 (rw) I/O Ports: 0x170-0x177 (rw) I/O Port: 0x376 (rw) I/O Ports: 0x2240-0x224f (rw) IRQ: 16 (26 events) Module Alias: "pci:v00008086d0000266Fsv0000103Csd0000099Cbc01sc01i8A" Driver Info #0: Driver Status: ata_piix is active Driver Activation Cmd: "modprobe ata_piix" Driver Info #1: Driver Status: ata_generic is active Driver Activation Cmd: "modprobe ata_generic" Config Status: cfg=new, avail=yes, need=no, active=unknown > I'm not hoping for a specific fix to my particular problem especially with > so little information presented.

I presume it is not possible to run something like a subhurd with rumpdisk on a system using gnumach ide to already drive the disk? Regards, João
