I am too having the same thing appear, it started once i added my advansys
based Ultra Wide SCSI adapter, all the serial port identities dsiappeared
from the IRQ list but functionality is still there, i have COM1,2,3,4 on
IRQ's 4,3,7,9 respectivly (extra 2 are a ISA 2 x ST16650V2 fully
jumperable IO card), procinfo shows:

irq  0:    984034 timer                 irq  7:        22
irq  1:         2 keyboard              irq  9:      3342
irq  2:         0 cascade [4]           irq 11:     47697 advansys, eth0
irq  3:   1825934                       irq 14:     23321 ide0
irq  5:         1 soundblaster          irq 15:     13057 ide1
irq  6:         3

and /proc/interrupts show:

           CPU0
  0:    1048426          XT-PIC  timer
  1:          2          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  3:    1943828          XT-PIC
  5:          1          XT-PIC  soundblaster
  7:         22          XT-PIC
  9:       3342          XT-PIC
 11:      56781          XT-PIC  advansys, eth0
 14:      28755          XT-PIC  ide0
 15:      14328          XT-PIC  ide1
NMI:          0
ERR:          0

The above was taken from my system whist running kernel 2.4.4 (release)
it also appeared on 2.4.3 (release) after i added the advansys card, which
has appeared to have jumped on irq 11 along side the DEC Tulip ethernet
card. (The advansys replaced a sym53c810a card which used to sit on irq
10)

Maybe its something to do with IRQ sharing?

Regards, Jim.
