Subject: [Bug 15007] New: SCSI host adapter's scatter-gather list size Issue
Date: Fri, 8 Jan 2010 11:07:49 GMT [thread overview]
Message-ID: <bug-15007-11613@http.bugzilla.kernel.org/> (raw)
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@vger.kernel.org
ReportedBy: nick.cheng@areca.com.tw
CC: akpm@linux-foundation.org
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??
Thanks,
