SubjectRe: Promise FastTrak TX4 losing interrupts (with apic mode)
replying on an old thread
looks like i have the same problem as below

kernel 2.4.20 intel sc7500cw mainbord (dual xeon)
booting with noapic appended resolves the lost interrupt messages
(only happens on the TX4 disks (there is also an onboard
FastTrak100(2channel)which works ok)

I don't use the promise raid code, just using the card to use some extra
ide channels for my sw raid5

i get exactly the same error when booting :

hde: lost interrupt
hde: lost interrupt
ide_dmaproc: chipset supported ide_dma_lostirq func only: 13
hde: lost interrupt
unknown partition table
hdg: lost interrupt
hdg: lost interrupt
ide_dmaproc: chipset supported ide_dma_lostirq func only: 13
hdg: lost interrupt
unknown partition table
hdi: lost interrupt
hdi: lost interrupt
ide_dmaproc: chipset supported ide_dma_lostirq func only: 13
hdi: lost interrupt
unknown partition table

moved arround the tx4 card between pci slots (and busses (mainbord has 3
pci busses)) but keeps getting the same error
the tx4 always gets irq48 (not shared with anything else)

only booting with noapic fixes it
(are there any negative point when running in 'noapic mode' ?(besides
losing high irq's))
