I have been able to reproduce them as well. Following kernels deadlocked in less than 6 hours of abuse: - mainline 2.4.20 - mainline 2.4.21-pre3 Following kernels survived 20 hours of abuse: - Red Hat 2.4.20-2.21 > >Can you re-run your hanging tests cases with this patch applied to > >loop-AES-v1.7a?

Loop code appears to be okay in loop-AES-v1.7a. Can you try applying attached patch to 2.4.21-pre3 kernel and try again? It is based on Andrea Arcangeli's fix-pausing-2 patch. Here is original version: ftp://ftp.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.20rc2aa1/9980_fix-pausing-2 Regards, Jari Ruusu <jari.ruusu@pp.inet.fi>
