Can you give a bit more detail here? If what you mean is that the driver
for the card generated an OS panic when a drive failed, that's not
necessarily the firmware at all. I know I had problems with the Areca
cards under Linux until their driver went into the mainline kernel in
2.6.19, all kinds of panics under normal conditions. Haven't seen
anything like that with later Linux kernels or under Solaris 10, but then
again I haven't had a disk failure yet either.
