I have been trying to get anyone to respond to this issue as well.
I have offered both my time and the fact that I own many many Mylex
cards and would be happy to test, mail them out, perform magic
tricks, etc., to get some assistance.
Greg Loomis (of vinum fame) helped me out with a problem with
Mylex RAID's and vinum, only to have it fail again at this point.
(He is not responsible for this error or Mylex drivers; I only
mention this because he bailed me out last minute and then I still
got stuck with this driver issue, which was a bummer for me).
The problem is confirmed to not be present at 4.2-RELEASE. I have
back-ported Greg's fix for 4.2-RELEASE to get around the Mylex
problem for the time being.
I am not using the Mylex card as a boot device if that is of concern.
I only have Mylex cards with 2.73 firmware or lower (they are mostly
scavenged cards from Alpha's now running in Intel chassis). It is possible
that others do not experience with problem with other Mylex cards besides
the 960's, or with newer firmware.
Anyone comment on what has changed, or can the Mylex driver maintainer
(looks to be msmith?) offer any thoughts for us stuck with cards that no
longer work?
Thanks,
-matt
