I have a number of Dell Poweredge 750 servers here. Since upgrading them to 6.0-RC1 (cvsup as of early on 10/21) from 5.4-STABLE, I'm getting a new log message at boot time. Here's an extract: atapci0: <Intel 6300ESB SATA150 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xfea0-0xfeaf at device 31.2 on pci0 atapci0: Reserved 0x10 bytes for rid 0x20 type 4 at 0xfea0 atapci0: failed to enable memory mapping! ata0: <ATA channel 0> on atapci0 atapci0: Reserved 0x8 bytes for rid 0x10 type 4 at 0x1f0 atapci0: Reserved 0x1 bytes for rid 0x14 type 4 at 0x3f6 ata0: reset tp1 mask=03 ostat0=50 ostat1=00 ata0: stat0=0x00 err=0x01 lsb=0x14 msb=0xeb ata0: stat1=0x00 err=0x04 lsb=0x00 msb=0x00 ata0: reset tp2 stat0=00 stat1=00 devices=0x4<ATAPI_MASTER> ata0: [MPSAFE] ata1: <ATA channel 1> on atapci0 atapci0: Reserved 0x8 bytes for rid 0x18 type 4 at 0x170 atapci0: Reserved 0x1 bytes for rid 0x1c type 4 at 0x376 ata1: reset tp1 mask=03 ostat0=80 ostat1=80 ata1: stat0=0x50 err=0x01 lsb=0x00 msb=0x00 ata1: stat1=0x50 err=0x01 lsb=0x00 msb=0x00 ata1: reset tp2 stat0=50 stat1=50 devices=0x3<ATA_SLAVE,ATA_MASTER> ata1: [MPSAFE] The complete dmesg is here: http://www.tmk.com/transient/pe750-dmesg.txt This happens on a number of different configurations. The above dmesg is from a box with a pair of SATA drives on the built-in SATA controller and a CD-ROM on the ATA side of the controller; it also happens on a box with only the CD-ROM (that system has SCSI disks). The message seems to be harmless, but is confusing. I searched the archives and didn't find any discussions relevant to this problem on 6.0-RC1, so I'm posting here. I can provide remote access to the system (including BIOS console) to de- velopers if needed. Terry Kennedy http://www.tmk.com terry@tmk.com New York, NY USA
