  • Fix fractured block problem (implemented by adding blk-atomic feature).
  • Add several performance and scalability improvements for SMP systems.
  • Fix a longstanding TCP problem that can lead to hanging SSH sessions.
  • Fix possible data exposure and data corruption caused by abusing O_DIRECT.
  • Prevent statfs overflow for huge NFS filesystems.
  • Enable support for more than 256 SCSI hard disks by default on SMP systems.
  • Fix problem in O_DIRECT implementation when reading files with holes in it.
  • Fix possible lockup on full reiserfs when blocksize != pagesize.
  • Fix possible oops when trying to free pages in async-I/O.
  • Fix longstanding off-by-one error in keventd initialization that can lead to system freeze.
  • Fix MD RAID1 oops when a disk has failed.
  • Fix possible data loss on umount when the filesystem is mounted with "data=journal" option.
  • Prevent possible ETXTBSY errors.
  • Fix scheduler problem where an RT task can hang the system.
  • Fix O_DIRECT for filesystems with a blocksize less than 4k.
  • Fix system crash when using bigpages under certain circumstances.
  • Add workaround for AMD errata #56 for 768MPX chipset.
  • Fix problem in SCSI midlayer that leads to inferior performance for some AIC7xxx adapters.
  • Fix handling of Unisys ES7000 interrupt override for PCI range.
  • Fix file mark handling bug in osst that breaks some backup programs.
  • Fix LVM major checking in XFS.
  • xfs ACLs: return ERANGE instead of E2BIG if number of entries overflows.
  • Fix bug in file truncate for async-I/O
  • Fix SMP race that can lead to corrupted or lost data on power failure
Driver updates
  • Update LSI Fusion-MPT driver to
  • Update aacraid driver to 0.9.9-axb03.
  • Update Syskonnect driver sk98lin to v6.02.
  • Add bcm4400 network driver 1.0.1.
  • Update bcm5700 driver to 5.0.17.
  • IBM ServeRaid driver downgraded to 5.11. Some machines seem to have problems when firmware version and driver version don't match (there is no firmware version 6.00 available yet). Use newer driver version 6.0.0 only on IA64..
  • Update cciss driver to 2.4.42.
  • Add preliminary support for IBM x445 ("RUTHLESS").
  • Update amd8111e network driver to version 3.0.0.
  • Update megaraid driver to 1.18e.

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system by using these commands:
rpm -Uvh k_deflt.rpm mkinitrd
In case you are using lilo, please make sure that you also execute the command
after installing the update and running mkinitrd for the system to remain bootable.
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
