Best guess would be non plain text (i.e. having html components).  vger
is pretty keen on eating those as part of its spam filtering.

The best docs we have is the source.  LSI can provide the reference
manuals under NDA.

You still need to turn off html email attachments, otherwise your
messages won't be accepted by the mailing lists.  It will be an option
like recipient wants text/plain only or something.

It looks like a standard error handling escalation sequence.  Why is
very hard to tell without the entire kernel log.  Why there wasn't a
recovery is also not clear.

There's not much else I can do.  If you post the entire kernel log, the
fusion people hang out on this list and might see something that
indicates what the problem is.

Re: need fusion driver guide

[linux linux]

HI James,

I got some idea about fusion driver from this link
http://bugzilla.kernel.org/show_bug.cgi?id=12195

And i found there is bug in fusion driver (kernel version 2.6.10) from this link
http://www.nabble.com/MPT-fusion-driver,-better-but-still-buggy-at-errors-handling-under-2.6-td1095505.html

yes its error handler sequence. But as describe into the above
link(http://www.nabble.com/MPT-fusion-driver,-better-but-still-buggy-at-errors-handling-under-2.6-td1095505.html)
that
2.6.xx  xx <= 11, enters an infinit loop attempting to reset the SCSI
        so the box gets unusable and requires a rough power cycle to recover.

So i think that is  the reason to restart the server(after "Attempting host
reset! )as a power cycle is required to recover.

when next time server was booting i got  some kernel messages on
recovery of SCSI. So recovery is done after reboot the server.

Still i do not know how to over come this bug fo infinite loop. If you
have any suggestion please let me know.
