http://bugzilla.kernel.org/show_bug.cgi?id=15007 Summary: SCSI host adapter's scatter-gather list size Issue Product: IO/Storage Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: SCSI AssignedTo: linux-scsi@xxxxxxxxxxxxxxx ReportedBy: nick.cheng@xxxxxxxxxxxx CC: akpm@xxxxxxxxxxxxxxxxxxxx Regression: No I found if I set scatter-gather table size as 1024 Areca's RAID controller, ARC1680, and then execute "mkfs.ext3 /dev/sdX" on a sas/sata volume which is formated as NTFS, it will kill the controller and let it restart. This issue pops up easily on Intel server board with multi-processors and so far can not be reproduced on a volume with a original Linux filesystem such as, ext3. I also found the issue is on the write command with 128 sg entries, each with 4K byte in length. As the command comes from the upper layer, it lacks data in the 128th sg entry. I exits from 2.6.18 to 2.6.32. I try to track kernel source code but so far there is no finding. The driver is ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/Linux/DRIVER/SourceCode/arcmsr.1.20.0X.15-90605.zip. Anybody can give it a try??
