Card reworked now and network wired, so using the new server actually. I haven't booted Linux on my Malta for a while now, but it turns out to work just fine, and your patch set does not regress it booting multi-user NFS-rooted over FDDI.
I note however that the system does not reboot properly:
sd 0:0:0:0: [sda] Synchronizing SCSI cache reboot: Restarting system Reboot failed -- System halted
which is a regression, and also the MMIO-mapped discrete CBUS UART (ttyS2) does not sign in anymore either:
Serial: 8250/16550 driver, 5 ports, IRQ sharing enabled printk: console [ttyS0] disabled serial8250.0: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A printk: console [ttyS0] enabled printk: console [ttyS0] enabled printk: bootconsole [uart8250] disabled printk: bootconsole [uart8250] disabled serial8250.0: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a 16550A
while long ago:
Serial driver version 5.05c (2001-07-08) with MANY_PORTS SHARE_IRQ SERIAL_PCI enabled ttyS28 at 0x03f8 (irq = 4) is a 16550A ttyS29 at 0x02f8 (irq = 3) is a 16550A ttyS30 at 0x0000 (irq = 20) is a 16550
(I don't know why the line numbers reported were so odd back then, but the standard character device major:minor numbers for ttyS0-2 just worked), so there's probably something wrong with platform device registration. ISTR using the CBUS UART as a console device at one point too.
