Hi. I am writting a small os base on x86 arch. I have just written a rtl8139 driver for my os.the device's interrupt vector is 11. When I run my os, I can 'ping' it through windows for a while. But after a few minutes, the rtl8139 network card has not produce any interrupt.
I can assure the os is not dead.Because it can receive the interrupt from PIT, and the Ticks in my os is increasing. I also check the device's status, it also do not have any problem.
I have tried a lot of method, still can not solve this problem.
Please give me some help. thanks.
