Hi,
I'm busy hacking into the arm26 port (Archimedes, A5k) in 2.5.69 and I've hit a brick wall. I have fixed support for initrd, fdd and hdd on the A5k (amongst other things), but I can't get any of them to boot into a root fs.
If I try booting into root=/dev/hda1 (which contains a valid FS that I can boot with a 2.0.31 kernel), I get the following:
{snip} Floppy drive(s): fd0 is 1.44M, fd1 is 1.44M FDC 0 is an 8272A RAMDISK driver initializer; 16 RAM disks of 4096K size 1024 blocksize Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 50MHz system buss speed for PIO modes; override with idebus=xx hda: Conner Peripherals 120MB - CP30104H, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 11 hda: task_no_data-intr: status=0x51 { DriveReady SeekComplete Error } hda: task_no_data-intr: status=0x54 { DriveStatusError } hda: hda1 hda2 Console: switching to colour frame buffer device 80x60 i2c /dev entries driver module version 2.7.0 (200221208) Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)
If I try booting into initrd (no arguments), I get same with the following at the end:
VFS: Insert root floppy disk to be loaded into RAM disk and press ENTER VFS: Insert root floppy and press ENTER Kernel panic: VFS: Unable to mount root fs on fd0
A point to note is that the machine then can't read its disks in RISC-OS until it has been switched off. Hard reset does nothing. Also, the hda: hda1 hda2 line doesn't contain a partition type label (it's DOS), which strikes me as odd. I do have DOS partition support compiled in. Overriding with idebus=25 makes no difference by the way.
I really don't have a clue where this problem could be caused... does anyone have any pointers for me?
Regards,
John
