lost interrupt and inb()

hello all,

i tried to made a program in the form of a module. This program would attempt to read/poll status register of IDE until the value for the status register is 0x50. 

here is the algorithm:

save_flag();
disable_interrupt();
poll_or_read_or_get_input_from_IDE_status_register();
enable_interrupt();
restore_flags();

this program would run fine, but after the program is finished executing, it would display a message:
ide_dmaproc: chipset supported ide_dma_lostirq func only: 13
hdc: lost interrupt

the OS doesn't hang. because normal operation would resume after this program exit.
OS=linux 7.3, kernel=2.4.18-3

my question is:
how can i solve this error such that the error message would not appear anymore?

i have lots of other questions, but that of the above is the most important..

hope to hear your reply,

-Ana
