Hi,
I ran the following two scripts simultaneously on 6.2-PRERELEASE SMP box
(cvsup'ed today).
----------------------------------------
#!/bin/sh
while true; do
ls -lR / > ls_result.txt
done
----------------------------------------
----------------------------------------
#!/bin/sh
while true; do
ls -lR / > ls_result2.txt
done
----------------------------------------
After a while (about 5 minutes), I suspended and killed the both, and
ran "ps". As the result, "ps" locked up. No response and no output.
To make matters worse, I could not login anymore...
This is 100% reproducable on SMP, but no problem when using Non-SMP kernel.
