The FreeBSD Release Engineering Team is proud to announce the
availability of FreeBSD 5.3-BETA4. This is the fourth BETA of the 5.3
release cycle. It is intended for early adopters and those wishing to
help find and/or fix bugs. The 5.3 release cycle will continue with
weekly BETA builds while bugs are being fixed and features finalized.
The schedule is at http://www.freebsd.org/releases/5.3R/schedule.html.
Be sure to check the "Known issues" below, there are known problems
still being worked on at this time. At this time the Release
Engineering team anticipates releasing at least one more BETA snapshot
before the first Release Candidate. The schedule will be updated for
Fixed and Enhancements made since BETA3:
- ATA works on sparc64 and ia64 again. This was due to several bugs in
busdma. sparc64 no longer defaults to having ATA DMA be off.
- Better support for statically linked threaded programs in GDB.
- Support for more Broadcom and Realtek-based NICs
- Fixes for MSDOS internationalization support.
- Many fixes for ATA including speed fixes for ICH* chips, better error
recovery, and better support for devices that respond as both master
- Various locking fixes for AIO, the network stack, and socket polling.
- The default scheduler is now 4BSD. The switch was made in the
interest maximizing stability for 5.3. Users are still encouraged to
try the the ULE scheduler, though known bugs exist with it when
PREEMPTION is also turned on.
- Kernel debugging and malloc debugging options have been turned off for
the remainder of the RELENG_5 branch.
- Merge of the massive scheduler cleanup and bug fixes from 6-CURRENT.
This addresses a number of stability problems that have existed for
over 2 months including deadlocks, randomly aborted processes, and
panics. This also improves the performance of the 4BSD scheduler by
keeping idle processors busy during light and medium loads.
Known issues in this release:
- There are scattered reports of data corruption on SMP systems under
high load. This could be due to a known bug in the gvinum subsystem,
but it could be due to unknown factors. We are investigating this and
hope to correct it soon.
- pst(4) is known to cause a system panic during the boot time.
- The Synaptics Touchpad mouse support is known to have issues with
responsiveness. It can be disabled with 'hint.psm.0.flags="0x200"' in
"/boot/device.hints". This will be resolved for the release.
- There are reports of packet corruption with the nge(1) driver when the
network stack is run without Giant. These are being investigated.
A complete list of defects that will be fixed for the release can be
found at http://www.freebsd.org/releases/5.3R/todo.html.
For people wishing to upgrade older systems using cvsup(1) and the
procedure described in src/UPDATING the CVS tag to use is RELENG_5
at this point. Note that like all RELENG_X branches this is an
active development branch. We do not recommend those branches for
normal use (for normal use RELENG_X_Y branches are more appropriate,
e.g. RELENG_4_10 is the current stable branch).
