This makes no sense at all. I would have guessed that busybox workd
and voyage did not!
voyage:
cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:0 tx:4513 rx:139 oe:3 RTS|CTS|DTR|DSR|CD
1: uart:unknown port:000002F8 irq:3
cat /proc/interrupts
CPU0
0: 265852 XT-PIC-XT timer
2: 0 XT-PIC-XT cascade
10: 116 XT-PIC-XT eth0
11: 1 XT-PIC-XT ehci_hcd:usb1, ohci_hcd:usb2
ok, uart has irq 0 and there is no irq for it.
busy:
cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:0 rx:0 RTS|CTS|DTR|DSR|CD
1: uart:unknown port:000002F8 irq:3
cat /proc/interrupts
CPU0
0: 6011 XT-PIC-XT timer
2: 0 XT-PIC-XT cascade
4: 0 XT-PIC-XT serial
actually makes sense and compares to factory:
serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:825 rx:7 RTS|CTS|DTR|DSR|CD
1: uart:unknown port:000002F8 irq:3
cat /proc/interrupts
CPU0
0: 11770 XT-PIC-XT timer
2: 0 XT-PIC-XT cascade
4: 70 XT-PIC-XT serial
but voyage gets this:
Console: colour dummy device 80x25
console [ttyS0] enabled
busy gets
Console: colour dummy device 80x25
console [tty0] enabled
console [ttyS0] enabled
busy+v3 gets
Console: colour dummy device 80x25
console [ttyS0] enabled
oh boy. . voyage/v3 gets this:
Serial: 8250/16550 driver $Revision: 1.90 $ 2 ports, IRQ sharing enabled
�serial8250: ttyS0 at I/O 0x3f8 (irq = 0) is a 16550A
this is I am pretty certain an IRQ foulup. Why are busy and voyage so
totally different?
how do the .config files compare? does factory bios have ACPI (it
would appear not).
