Hello, I have experienced an I/O lockup on my dual Xeon server with megaraid adapter when kernel was compiled with highmem and highmem i/o. It happened during compilation of mysql with no other load. Then I recompiled the kernel wo/highmem and everything is stable. As, this server is now in production on different location I cannot do much testing except giving detailed hw info. 00:00.0 Host bridge: Intel Corporation: Unknown device 254c (rev 01) 00:00.1 Class ff00: Intel Corporation: Unknown device 2541 (rev 01) 00:03.0 PCI bridge: Intel Corporation: Unknown device 2545 (rev 01) 00:03.1 Class ff00: Intel Corporation: Unknown device 2546 (rev 01) 00:1d.0 USB Controller: Intel Corporation: Unknown device 2482 (rev 02) 00:1d.1 USB Controller: Intel Corporation: Unknown device 2484 (rev 02) 00:1d.2 USB Controller: Intel Corporation: Unknown device 2487 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801BAM PCI (rev 42) 00:1f.0 ISA bridge: Intel Corporation: Unknown device 2480 (rev 02) 00:1f.1 IDE interface: Intel Corporation: Unknown device 248b (rev 02) 00:1f.3 SMBus: Intel Corporation: Unknown device 2483 (rev 02) 01:0c.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 02:1c.0 PIC: Intel Corporation: Unknown device 1461 (rev 04) 02:1d.0 PCI bridge: Intel Corporation: Unknown device 1460 (rev 04) 02:1e.0 PIC: Intel Corporation: Unknown device 1461 (rev 04) 02:1f.0 PCI bridge: Intel Corporation: Unknown device 1460 (rev 04) 03:04.0 SCSI storage controller: Adaptec: Unknown device 801f (rev 03) 03:04.1 SCSI storage controller: Adaptec: Unknown device 801f (rev 03) 04:02.0 RAID bus controller: Symbios Logic Inc.
