Unfortunately, contrary to previous messages, no 2.4.1 final release yet, but already a pre-patch! See also this update. As always, a kernel update applies to all platforms, not just i386.
And again a warning: these kinds of patches are in the alpha stage of development and are therefore (sometimes) not stable. Only something for advanced users and other daredevils . And of course the changelog:
Get non-cpuid Cyrix probing right (it’s not a NexGen)
Jens Axboe: cdrom tray status and queing cleanups
AGP GART: don’t disable VIA, and allow i815 with external AGP
Coda: use iget4() in order to have big inode numbers without clashes.
Fix UDF writepage() page locking
NIIBE Yutaka: SuperH Update
Martin Diehl and others: SiS pirq routing fixes
Andy Grover: ACPI update
Andrea Arkangeli: LVM update
Ingo Molnar: RAID cleanups
David Miller: sparc and networking updates
Make NFS really be able to handle large files
