(yeah, but there were a truckload of other changes as well) Looking at your data, _my_ first suspect would be the 2.6.22->2.6.23 futex changes. I'd revert all of the changes to kernel/futex.c and kernel/futex_compat.c, and see if the problem went away. If it didn't, I'd then do a full git bisect to nail it down. -Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Not necessarily so if kernel version indeed makes the difference between hung install and successful completion. Perhaps he has any tasks stuck in 'D' state? If so, SysRq-t output for these would be a good thing to collect. What leads him to suspect the process scheduler, etc. More details are needed.
