Recently our university has purchased some new servers. Among them, there are one Dell PowerEdge 2650 with two Pentium4-XEON 2G installed, and 2GB of RAM. No matter if the memory is limited to 256MB, or if the HyperThread is disabled or enabled. The server has AIC 7899 SCSI controller, and Dell Extensible RAID Controller(LSILogic MegaRAID having 128MB RAM on it) installed. When booting from 5.0-RC-20021213 CD-ROM, the system stops to respond after the following line is displayed on screen: amr0: <LSILogic MegaRAID> mem 0xf0000000-0xf7ffffff irq 5 at device 0.0 on pci3 I have tried 4.7-STABLE, when ANY ONE of(and of course combined) the following options enabled, the system hangs on amr0 too: ENABLE_SSE SMP (with APIC_IO) makeoptions CONF_CFLAGS=-fno-builtin options MAXDSIZ="(2048*1024*1024)" options MAXSSIZ="(2048*1024*1024)" options DFLDSIZ="(2048*1024*1024)" What's more, amr(4) panics on HP6000 with the MegaRAID having 32MB RAM: amr0: <LSILogic MegaRAID> mem 0xe0000000-0xefffffff irq 5 at device 3.1 on pci4 Fatal trap 12: Page fault in kernel fault virtual address = 0xde fault code = supervisor read, no page present instruction pointer = 0x8:0xc01a8229 stack pointer = 0x10:0xc0b0f9fc frame pointer = 0x10:0xc0b0fa0c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, grow 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 0 (swapper) kernel: type 12 trap, code = 0 stopped at amr_alloccmd+0x19: cmpl $0, 0(%ecx) This behavior doesn't appear on 5.0-DP1, I have to say, that DP1 doesn't have the same problem. But DP2 seemed to have the same problem, and all -CURRENT from that time, including all recent RCs, does have the problem. >How-To-Repeat: Boot from FreeBSD 5-CURRENT installation CD-ROM on Dell PowerEdge 2650, the system hangs immediately after the following line: and the keybord stops to respond anything, including CapsLock. Seemed that the system completely hangs. >Fix: Currently unknown, because I have final exam in these weeks. But I would be glad to help work out this problem in January 2003, if needed, as I am familiar with i386 assembly language, C and C++ language, and programming with hardware. I think if this problem continues, the release of 5.0 should be considered to be delayed, as LSI MegaRAID is widely used around the world. _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 >Release-Note: >Audit-Trail: >Unformatted: >on -STABLE To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
