The information below is from lspci and /proc/scsi/scsi of Linux 2.2.19, in that order, all Kernels have been compiled on a Duron/800 SuSE 7.0 Linux box (running gcc 2.95.2). Machine #1: Pentium-II (Klamath) 00:09.0 SCSI storage controller: Adaptec AIC-7881U Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: SEAGATE Model: ST34572W Rev: 0718 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: SEAGATE Model: ST39140W Rev: 1498 Type: Direct-Access ANSI SCSI revision: 02 Machine #2: Pentium-II (Deschutes) 00:09.0 SCSI storage controller: Adaptec AIC-7881U Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: SEAGATE Model: ST34572N Rev: 0784 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: IBM Model: DCAS-32160 Rev: S65A Type: Direct-Access ANSI SCSI revision: 02 These have further devices (CD writer, CD-ROM drive), and these machines are 100% in 2.2.19. With 2.4.3 and 2.4.4-pre8, I get this problem (pencil & paper copy for Machine #2, DO NOT "grep"): AIC 7XXX EISA/VLB/PCI SCSI HBA DRIVER 6.1.5 aic7880: wide Channel A, SCSI ID=7, 16/255 SCBs scsi0: SCSI host adapter emulation for IDE devices PCI: found IRQ 5 for dev 00:09.0 scsi1:0:0:0: Attempting to queue an abort message. Command found on device queue aic7xxx_abort returns 8194 Then, the Kernel detects the SECOND SCSI disk and attaches it as sda (Linux 2.2 would mount that as sdb), the first disk is "gone" (Linux 2.2 would mount that as sda). Regretfully, my root partition is on the FIRST SCSI disk, so the kernel panicks since it cannot mount /. That's all I copied in a hurry, maybe it's sufficient to debug, if not, I can try to grab a null modem cable and catch the full sequence; I'd be glad if someone could mention the "canonical" aic7xxx LILO append parameters for a full debug trace in that case. Bottom line: I'm not buying Adaptec SCSI host adaptors ever again. -- Matthias Andree
