Since {{kernel link|rhel6-testing|042stab054.5}}:
* rebased on 2.6.32-220.13.1.el6 RHEL6.2 kernel (security, bug fixes, and enhancements, see below)
* [fuse] our fuse O_DIRECT support implementation has been removed, Red Hat added the support
* [megaraid_sas] mask off flags in the ioctl path to prevent memory scribble with older MegaCLI versions ({{B|2240}})
* [atl1] kernel panic fixed in case of DMA errors
* [scheduler] warning added if huge IPI latency is detected (debug for PSBM-11683)
* [timer] kernel panic in timer interrupt in kexec on nodes with buggy BIOS fixed (PSBM-12579)
* [memory reclaimer] possibility to use sync writeback in memory reclaimer, basically this should make nodes much more responsive on high memory pressure (PSBM-11683, {{B|2188}})
* [oom] OOM priorities configuration has been reworked completely (PSBM-12263)
* [cgroups] kernel panic in devcgroup_seq_read() has been fixed (PSBM-12254)
* [cpt] task credentials fix
* [sheduler stat] /proc/uptime should now show correct idle time inside CT (PCLIN-30774)
* [ploop/pcs] max disk-space preallocation on PCS is limited to 128MB now (independent of ploop cluster-block size)
