hi all .

i am facing a issue with centos recently :

after every boot i receive the following message in terminal :

Sep 19 13:13:02 station2 kernel: irq 50: nobody cared (try booting

with the "irqpoll" option)

Sep 19 13:13:02 station2 kernel: [<c044e6fa>] __report_bad_irq

And immediately after it my external usb drive vanishes from the nautilus file browser and i get messages like this in /var/log/messages :

and the usb drive does not show up in nautilus any more. Then i have to reboot and after logging into x the drive shows up .but again after some time the same thing happens.

as someone suggested in the list,i add the "irqpoll" option to kernel line. after the system booted i log into X with tty1 also login as root with the command " tail -f /var/log/messages" for monitoring . After 10 to 20 minutes i got the same message again but this time immediately the system froze up !

i tried it 5 times now and each time is the same result.i also noticed that the system was behaving very slowly till the message came up like usually folder copy operation - i usually get 70-90MB/s according to vmstat 1 comand, but with irqpoll the maximum i noticed was like 10MB/s.

here is ouput from lspci -v :

my motherboard is asus m2n-vm dvi .I have updated the bios to the latest version and the bios settings are default. I did not change any option. and my os is fully up-to-date.

just out of curiosity, i recently compiled a kernel from 2.6.26 tree and the problem did not manifest itself with the desktop running 24 hours.

so is this a bug in the current centos kernel ?
