apport information
** Tags added: apport-collected uec-images
** Description changed:
We have observed that OS is sending the IO's (SCSI Read/Write) with incorrect
Scatter Gather Buffer address .
i.e
OS is sending the IO with 64 bit Scatter Gather Buffer address , such
that if we add the length with buffer address then it causes the roll
over .
Here is the data we captured in our driver (Printed the SGE details which was
sent by OS)
sgl_ptr->Address = fffffffffffff000
[14547.313240]
sgl_ptr->Length = 1000
[14547.313241]
sge_count = 18
[14547.313242]
cmd->index = 9d9
Note : This issue is observed only when virtualization is enabled
Product : Broadcom (LSI) Megaraid H840 controller
