Here are 3 patches for the mpt fusion driver.
Hello Bernd,
I am looking mpt fusion backport fixes for the LSI 53C1030 that will run with
Linux kernel 2.6.27.62. Current version is 3.04.07. Our problem is that running
on VMWare VSphere, with the SAN heavily loaded, we get SCSI timeouts.
Ex. mptscsih: ioc0: attempting task abort! (sc-ffff...)
sd 0:0:0:0: [sda] CDB: Read (10): 28 00 ...
mptscsih: ioc0: task abort: Success (sc=ffff...)
The system hangs for 30 seconds on each one.
I see comments/patches here: http://comments.gmane.org/gmane.linux.scsi/48215
Do you have source that would work for 2.6.27.62?
is there a chance you could use the the mpt-4.x driver? The other simple
way would be to use the driver from the SLES10 kernel (SLES10 without
any service pack, so 2.6.27).
I think you could simply replace the drivers/message/funsion directory.
I definitely cannot recommend to use a more recent kernel, as I know
from Q-Leap that recent kernels run into DV (domain validation) races,
which they 'solved' by introducing simple sleeps into the code.
I'm still in contact with Q-Leap, but decided to take another job some
time ago....
Cheers,
Bernd
