2.4.25 compiled without SMP and provided only as example.
If you delete the `return -ENODEV' line in drivers/serial/8250.c,
around line 1262:
/*
* At this point, there's no way the LSR could still be 0xff;
* if it is, then bail out, because there's likely no UART
* here.
*/
if (!(up->port.flags & UPF_BUGGY_UART) &&
(serial_inp(up, UART_LSR) == 0xff)) {
printk("ttyS%d: LSR safety check engaged!\n", up->port.line);
return -ENODEV;
}
does that fix it up?
No, removing that will not fix it - this is a check which detects if the port has vanished underneath us. As the comment says, if the LSR is 0xff, then there _is_ _no_ _port_ here anymore. I suspect that the ISAPNP code isn't finding the port for some reason. Maybe seeing the output of whatever gives PNP information would give a hint? (Is that lspnp or some random procfs file?) No, it doesn't help. What additional info should I post here? |
