Hi. Although this would make this Mail redundant, I deeply hope this is a known Problem. Since several Days I am trying to install Debian 2.1 on my System, with little success. Since I am NOT a Kernel Developer, I have found no way to get around this myself. The Problem persists with all Kernel versions *HIGHER* 2.0.34 and the AHA- 2940 FAST-SCSI Adapter w/ NVRAM, BIOS Version 1.21 (the only one I have) To me it looks like the almost-complete-rewrite made since then has broken something in the Area of the Sequencer. While reading this i realize it sounds like a SCSI-Newbie-Insufficent- Termination-Or-Something-Problem, I may assure you it is *not*. - Driver downloads 10 more Sequencer Code Bytes than usual (409 on 2.0.34, 419 on higher versions) - Last SCSI Disc getting reflected 3 times. - On Startup, I get timeouts and bus resets, then the kernel sometimes actually boots; then occasional bus resets while working, making work impossible; umount mostly halts the machine. Output of /proc/scsi/scsi for 2.0.34: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: Model: DFRSS2F Rev: 4B4B Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: TOSHIBA Model: CD-ROM XM-3701TA Rev: 3615 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: TEAC Model: CD-R55S Rev: 1.0J Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: SEAGATE Model: ST34520N Rev: 1281 Type: Direct-Access ANSI SCSI revision: 02 Output of /proc/scsi/aic7xxx for 2.0.34: Adaptec AIC7xxx driver version: 5.0.19/3.2.4 Compile Options: AIC7XXX_RESET_DELAY : 15 AIC7XXX_TAGGED_QUEUEING: Adapter Support Enabled Check below to see which devices use tagged queueing AIC7XXX_PAGE_ENABLE : Enabled (This is no longer an option) AIC7XXX_PROC_STATS : Enabled Adapter Configuration: SCSI Adapter: Adaptec AHA-294X Ultra SCSI host adapter Narrow Controller PCI MMAPed I/O Base: 0xffaef000 Adaptec SCSI BIOS: Enabled IRQ: 11 SCBs: Active 0, Max Active 1, Allocated 30, HW 16, Page 255 Interrupts: 4033 BIOS Control Word: 0x19b6 Adapter Control Word: 0x0018 Extended Translation: Enabled Disconnect Enable Flags: 0x00ff Tag Queue Enable Flags: 0x0000 Ordered Queue Tag Flags: 0x0000 Default Tag Queue Depth: 8 Tagged Queue By Device array for aic7xxx host instance 0: {255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255} Actual queue depth per device for aic7xxx host instance 0: {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1} [Stats deleted] By no means I managed to get this information with the new Driver, but IMHO that shouldn't matter anyway. I tried 2.0.36 as well as 2.2.5 Kernel versions, both no go. I would be very pleased if this Problem could be dealt with, and would like to know if other people are experiencing the same trouble with their 2940, and how they got around it. Many thanks in advance! I am under pressure with this one, friends. ben ## CrossPoint v3.11 ## To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
