    Hi

When boot is successfull (with 2.4.19-pa22), it discover 5 serial board
....
....
Redundant entry in serial pci_table.  Please send the output of
lspci -vv, this message (103c,1048,103c,1049)
and the manufacturer and name of serial board or modem board
to serial-pci-info@lists.sourceforge.net.
ttyS00 at iomem 0xfffffffff8000000 (irq = 132) is a 16550A
ttyS01 at iomem 0xfffffffff8000008 (irq = 132) is a 16550A
ttyS02 at iomem 0xfffffffff8000010 (irq = 132) is a 16550A

ttyS03 at iomem 0xfffffffff8005000 (irq = 133) is a 16550A
ttyS04 at iomem 0xfffffffff8005008 (irq = 133) is a 16550A

Now when booting the latest kernel 2.4.20-pa10

Kernel Fault: Code=26 regs=000000004fbb11c0 (Addr=0000000000000008)

If I try to do some stack unwind it gives:
0x1013c5c4    call_console_drivers+0xc4
0x1013cc8c    release_console_sem+0x164
0x1027b3e4    start_pci_pnp_board+0xa4
0x1027bd64    serial_init_one+0xac

It is a trap 26 -> Data Memory Access right trap in call_console_drivers().
When dissamble:

  b8:   37 dd 3f e1     ldo -10(sp),ret1
  bc:   e8 00 a0 00     b,l c4 <call_console_drivers+0xc4>,%r2
  c0:   0e 60 10 98     ldw 0(sr0,r19),r24
  c4:   08 06 02 5b     copy r6,dp    -> panic while accessing dp
  c8:   53 c2 3e e1     ldd -90(sp),rp

If someone as any idea........

Thanks.
