I wonder if rather than the intermittency being time-based, it is

lookup code?


Just a data point: I met the same problem with 2.6.12-rc5, using
gcc 3.3.4.
I think it's time-based issue, because I was playing around with the initscripts, and the bug shows up when there are lots of modprobes in a short time.



I think this is not actually module loading itself, but a problem
between the fork/exec/wait code in nash and the kernel. The
commands which have problems are the ones which are not built
into nash. So this looks more like a problem with wait. This
would explain sleep fixing it and the fact that I have device
issues after module load.
