The company we bought from had the policy that you had to have paid
support to download firmware updates after the warranty expired.
The court case for them not being  free would be pretty bad if they
got sued, since after the warranty period they were still fixing bugs
that cause the product to not work  Really stupid stuff like whena
raid5/6 disk starts getting bad sector errors the firmware returns
WRONG data.  The
people coding it seem to assume the disk will fail to respond (rare)
and did not write code to handle a simple common bad sector.   The
crappy code of course "passed" testing because testing did not
simulate the real world and have bad sectors.   Typical bugs are in
the exception/error handling code.   The worst scsi bug I found (that
redhat fixed--actually it looked like a kernel.orig developer really
fixed it, 2+ years after we gave them kernel dump details) was when a
scsi command timed out and was being canceled (but competed while
being canceled) then a kernel corruption/crash happened.

We had the bug often because we had multiple SAN arrays zoned to the
same machine and sometimes under high load if 2 SAN arrays with say
8gbit ports each are trying to stuff data into a machine  8gbit port
then data can be lost, and the SAN is designed for an unreasonable
perfect world were data loss should not happen, but when it does
happen it is pretty bad.

The computer companies are lucky so far that they have not pissed off
any of their customers enough that they do sue them because the court
case would be ugly for the manufacturer as this entire ship software
out the door barely passing the simple basic test case (and failing if
anything happens--even stuff that is expected to go wrong) is not good
enough.
