comment freebsd 7.2 kern.threads.max_threads_per_proc doesn't change after reboot
kern.threads.max_threads_per_proc is read-write tunable so you should place it in /etc/sysctl.conf

comment Java causing kernel panic
It's kernel panic in interrupt context - most likely java is not a culprit there - just interrupt happen to strike in the middle of java execution.

comment ext4 production ready on kernel 2.6.32 (debian6)?
Bugfixes are already done by LTS (long term support) kernel maintainers. Backporting new hardware support and features is crucial for Enterprise distros, otherwise for example you would not be able to run RHEL5 on modern hardware at all. Also if RedHat would not backport features from recent kernels it will loose customers. Anyway just look at release notes of RHEL 6.5: access.redhat.com/site/documentation/en-US/… and look for has been added or support for.

By backports I meant porting linux kernel features from recent kernels back to 2.6.32 without breaking API/ABI e.g. new versions of drivers or sometimes new features.

It's worth mentioning that RedHat 2.6.32 has a bunch of redhat-specific backports from recent kernels, so it can not be compared to Debian's.
