Re: 2.4.xx IDE development policy

Andre et al,

Just to add some more positivity: I'm running 2.4.18-ac and 2.4.19-pre
and stable kernels (currently 2.4.19-rc3 vanilla) for a while now on my
fileserver. It has 1 onboard VIA and 2 PCI Promise controllers and a
total of 6 disks attached (every disk on its own cable). I kept the BIOS
versions of the Promise controllers up to date all the time. All disks
are running automagically - without passing kernel options - on their
max possible UDMA transfer rate, and even the 160Gb LBA48 disk is
behaving fine. The disks are in constant heavy use as fileserver for
500+ clients. With respect to IDE, the system is rock solid for a long
time now, and I have never ever seen even a little bit of data
corruption.
