Should I send more info? 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?
