Release Date : Fri May 19 09:31:45 EST 2006 - Seokmann Ju <[email protected]>
|
||||
Current Version : 2.20.4.9 (scsi module), 2.20.2.6 (cmm module)
|
||||
Older Version : 2.20.4.8 (scsi module), 2.20.2.6 (cmm module)
|
||||
|
||||
1. Fixed a bug in megaraid_init_mbox().
|
||||
Customer reported "garbage in file on x86_64 platform".
|
||||
Root Cause: the driver registered controllers as 64-bit DMA capable
|
||||
for those which are not support it.
|
||||
Fix: Made change in the function inserting identification machanism
|
||||
identifying 64-bit DMA capable controllers.

2. When INQUIRY with EVPD bit set issued to the MegaRAID controller,
|
||||
system memory gets corrupted.
|
||||
Root Cause: MegaRAID F/W handle the INQUIRY with EVPD bit set
|
||||
incorrectly.
|
||||
Fix: MegaRAID F/W has fixed the problem and being process of release,
|
||||
soon. Meanwhile, driver will filter out the request.
|
||||
|
||||
3. One of member in the data structure of the driver leads unaligne
|
||||
issue on 64-bit platform.
|
||||
Customer reporeted "kernel unaligned access addrss" issue when
|
||||
application communicates with MegaRAID HBA driver.
|
||||
Root Cause: in uioc_t structure, one of member had misaligned and it
|
||||
led system to display the error message.
|
||||
Fix: A patch submitted to community from following folk.
