The Red Hat* Linux* AS 3.0 32bit driver for the Intel(R) RAID Controller SRCU42X can be downloaded from the following URL: http://downloadfinder.intel.com/scripts-df/Detail_Desc.asp?agr=N&Inst=Yes&ProductID=1062&DwnldID=7410 -------------------------------------------------------------------- Please mention my question to the support team at Intel, here we go: -------------------------------------------------------------------- Dear support, i get really confused at this moment so i am contacting you, as the last possibility. We got the following Hardware for our end customer: Mainboard : Tyan Tiger - I7501R Rev S2735-8m V2.02 Intel Raid Controller SRCU42x, working in a 64 BIT Slot Operating System : Red Hat Enterprise Linux 3 ES (i386) with Update 2 I get confused with the Driver Section for this Operating System. Can YOU tell me the RIGHT HTTP Referer to the Driver for this Controller to get this working with the OS ??? -------------------------------------------------------------------- In fact, the system Freezes for a few seconds or totally crashes/ Hangs up so i must RESET the machine. Version-Release number of selected component (if applicable): 2.4.20.x 2.4.20.x SMP How reproducible: Always Steps to Reproduce: 1. Install SRCU42x Intel Raid Controller on a Tyan Tiger using the I7501 Chipset, with 2 XEON 2,8 GHz CPU�s, 2 GB RAM 2. Define RAID Level (it also appears at 0,1,2,3,4,5,50) 3. Install Linux ES using linux -dd on the IDE Harddisk 4. Install the Driver from the upper Intelsupport located in the text here 5. Stress the System with Network traffic to the RAID Volume My volume is called /dev/raiddisk Hyperthreading is enabled Harddisks : 6x 147 GB SCSI HD 320, working on a 160er backplane; Controlleracess settled up to 160m Actual Results: The system hangs or crashes during RAID Operation. When it moves out due normal Operation (save not to the RAID but to the IDE) it runs fine. Expected Results: WORKING SYSTEM with RAID 5 Additional info: MEGARAID : Flush 64 times in queue ... seems to be that the driver is unable to flush the cache ????? HINT if you can help me : I am a LINUX ES Newbie and my english is bad. please explain in details. I will attach the LOG Files of the SCSI Error messages tomorrow.
Created attachment 101808 [details] shows how mem decreases, buffer increases. stopped before freezing the machine. Ok, the problem seems to be the following : after pushing Files to the System the memory began to decrease. The buffersize increases, the memory USED increased caused by the buffers. Then, when 2GB are reached for buffers, the system freezes. HELP

Michael, I think it would be better for you to work with Intel support on this problem, since their driver is causing the problems.
