1 | Release Date : Fri May 19 09:31:45 EST 2006 - Seokmann Ju <sju@lsil.com> | ||
2 | Current Version : 2.20.4.9 (scsi module), 2.20.2.6 (cmm module) | ||
3 | Older Version : 2.20.4.8 (scsi module), 2.20.2.6 (cmm module) | ||
4 | |||
5 | 1. Fixed a bug in megaraid_init_mbox(). | ||
6 | Customer reported "garbage in file on x86_64 platform". | ||
7 | Root Cause: the driver registered controllers as 64-bit DMA capable | ||
8 | for those which are not support it. | ||
9 | Fix: Made change in the function inserting identification machanism | ||
10 | identifying 64-bit DMA capable controllers. | ||

62 | 2. When INQUIRY with EVPD bit set issued to the MegaRAID controller, | ||
63 | system memory gets corrupted. | ||
64 | Root Cause: MegaRAID F/W handle the INQUIRY with EVPD bit set | ||
65 | incorrectly. | ||
66 | Fix: MegaRAID F/W has fixed the problem and being process of release, | ||
67 | soon. Meanwhile, driver will filter out the request. | ||
68 | |||
69 | 3. One of member in the data structure of the driver leads unaligne | ||
70 | issue on 64-bit platform. | ||
71 | Customer reporeted "kernel unaligned access addrss" issue when | ||
72 | application communicates with MegaRAID HBA driver. | ||
73 | Root Cause: in uioc_t structure, one of member had misaligned and it | ||
74 | led system to display the error message. | ||
75 | Fix: A patch submitted to community from following folk. | ||
