| |
Hello,
I'm using Linux-2.4.2-ac27 SMP compiled with gcc version 2.95.2 20000220 (Debian GNU/Linux).
After an "insmod aic7xxx" "cat /proc/bus/pci/devices" works just fine. After an "rmmod aic7xxx" "cat /proc/bus/pci/devices" fails to produce any output and never finishes. Top show the process in R state taking as much CPU as it can get.
Killing the process doesn't do anything, rebooting is the only way to get rid of it. This problem does not happen with aic7xxx_old.
Strace shows a "read" on the fd of /proc/bus/pci/devices that never finishes.
My aic7xxx devices as reported by "lspci -vvv":
