(SCSI ATP870U)Various problems with atp870u.o
Last modified: 2008-08-01 12:22:52 EDT
Description of Problem: For various reasons, I replaced one of two Adaptec HBAs in a server with a card whose driver is detected as atp870u.o. See the lspci attachment for the card info, and the info on the remaining Adaptect HBA. This is a card with one bus with a wide side and a narrow side. Is this a supported SCSI HBA in RH? There are two problems two report in any case: During boot, occasionally the boot freezes after printing aec671x_detect: ACARD AEC-671X PCI Ultra/W SCSI-3 Host Adapter: 0 IO:c000, IRQ:5. The second problem is when the boot does proceed past the point, the SCSI CD-ROM driver is not detected. All the other narrow devices are detected, except for the CD-ROM device (the wide hard disk is always detected). The CD-ROM device is detected by the card's BIOS during POST, it's just never seen by the kernel. I moved the narrow cable to the remaining Adaptec HBA, and the CD-ROM drive (together with the other narrow devices that were moved with it) reappeared. Still collecting data to determine whether moving the narrow devices has eliminated the random boot lockup. Version-Release number of selected component (if applicable): 2.4.18-5-smp.
Created attachment 71385 [details] PCI bus.
Created attachment 71386 [details] SCSI bus.
It looks like moving the narrow devices off the ATP fixes the boot issue. So, to summarize, when there are both narrow and wide SCSI devices, this driver A) Hangs at boot-time initialization about 30% of the time. B) Does not see the narrow SCSI CD-ROM device.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
