I re-checked my serial woes I had two months ago with 2.3.26 and they
seem driver version related. Did not check against serial 4.90 which is
available separately, sorry. :-(
ttyS0..ttyS3 are hard-coded, non-IRQ-sharing 16552 chips (ISA),
ttyS4..ttyS7 are on a VSCom 400 PRO (4 * 16750, ISA, IRQ sharing,
software configurable, AST FourPort compatible, 921.6 kBaud). With
2.2.13 (4.27 serial driver) everything is smooth.
Here's what my boot scripts are trying to do:
running /sbin/setserial -b /dev/ttyS0 irq 4 autoconfig
running /sbin/setserial -b /dev/ttyS1 irq 3 uart 16550A
running /sbin/setserial -b /dev/ttyS2 port 0x3e8 irq 4 uart 16550A
running /sbin/setserial -b /dev/ttyS3 port 0x2e8 irq 3 autoconfig
running /sbin/setserial -b /dev/ttyS4 baud_base 921600 uart 16750 irq 10 port 0x180 ^fourport
running /sbin/setserial -b /dev/ttyS5 baud_base 921600 uart 16750 irq 10 port 0x188 ^fourport
running /sbin/setserial -b /dev/ttyS6 baud_base 921600 uart 16750 irq 10 port 0x190 ^fourport
running /sbin/setserial -b /dev/ttyS7 baud_base 921600 uart 16750 irq 10 port 0x198 ^fourport
running /sbin/setserial -b /dev/ttyS4 set_multiport port1 0x1c2 mask1 0xf match1 0xf
Here's what I get from the two autoconfig setserial invocations (using
ksymoops 0.6e): (two oopsen)
Warning in compare_ksyms_lsmod, module adlib_card is in lsmod but not in ksyms, probably no symbols exported
