SubjectUninterruptible sleep processes
The following code fragment will place the process in 
uninterruptible sleep on my 2.1.90 systems:

sd = socket (AF_INET, SOCK_DGRAM, 0);
/* the socket call completes OK */

bind(...) /* succeeds */
:
ioctl(sd, SIOCGIFCONF, (char *) interfaces);

The process hangs at the ioctl() call.

This problem occurs on a non-SMP system, kernel 2.1.90.
It does not occur at 2.1.79 or 2.0.29 kernels.

Any ideas?
