Description of problem:
serial device is named as ttyS01 instead of ttyS1
this bug was first introduced in 2.4.19pre7 and fixed later.
I found about it in LKML archives dated April 16th 2002.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
dmesg | more
Serial driver version 5.05c (2001-07-08) with MANY_PORTS MULTIPORT SHARE_IRQ
SERIAL_PCI ISAPNP enabled
ttyS01 at 0x02f8 (irq = 3) is a 16550A
Actual Results: there is no device named ttyS01, there are ttyS1 and others.
there is no way I can use my serial device with this kernel.
fixed for the next build
Fix confirmed with kernel-2.4.18-11.
