Hello, (can you CC me? i'm not on the list)
I have a LSI MegaRAID SAS 8204ELP card, and since it wasn't recognized by any
driver, i tried using the megasr driver supplied by LSI (it also supplies
open_source code with it), i had to modify the code a bit to get it to boot
with kernel-2.6.21 . but there's a very high iowait on it. i'm wondering if
the megaraid_sas driver is meant to be the driver for the same hardware as
megasr? would it help if i just added another PCI ID to the module and try
that one?
Sincerely,
Maarten Vanraes

Yeah you can try drivers/scsi/megaraid/megaraid_sas.c or
drivers/message/fusion/mptsas.c.
A URL to the megasr driver would be nice.
Also, please keep linux-scsi in CC (I added it), that's where this sort
of things is usually discussed.
