[Bug 240145] [smartpqi][zfs] kernel panic with hanging vdev

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240145

--- Comment #52 from Hermes T K <Hermes.TK@microchip.com> ---
Hi,

In freeBSD 13.0, while running  IO with blocksize 1MB , observed  a corruption
in SGL received.
Due to this corrupted SGL was leading to FW lockup. 
With this driver hangs & crashes.
Observed that the incomplete SGL is observed during IO with higher transfer
size.

Created a freebsd bugzilla ticket for this issue
:https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259129
But there is no update to this ticket till now. 

Workaround for this issue is to reduce the Maximum transfer size of the IO.
With the attached patch , i have reduced the tranfer size & was not observing
the 
issue.

Thanks & Regards
Hermes T K
