[root@penguin /root]# uname -r
2.2.19-3smp

This is 2.2.19 + the IDE patch. It is had this configuration for a few
years - and tends to go down with powercuts etc. rather than anything
else. No disk corruption.

There is another with a similar configuration which is on a UPS and has
a lot more uptime.

I'm just using SCSI at the moment on my 2.4 kernel BP6 box - but I never
noticed any problems with IDE when I was using it (I had to do a small
patch for a bug which made hdparm refuse to change back to mode4 once it
had gone down to a lower mode - this with 2.4.18 and lower.).
