From mboxrd@z Thu Jan 1 00:00:00 1970 From: Burkhard Bunk Subject: aic7xxx problem in 2.4.18-SMP Date: Tue, 21 May 2002 15:31:35 +0200 (MEST) Sender: linux-smp-owner@vger.kernel.org Message-ID: References: Mime-Version: 1.0 Return-path: In-Reply-To: List-Id: Content-Type: TEXT/PLAIN; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-smp@vger.kernel.org Cc: linux-scsi@vger.kernel.org Hallo, it took me some time to boot a SCSI system with the aic7xxx driver compiled into kernel 2.4.18-SMP. After the boot messages: ======================================================================== May 21 12:21:10 ficus2 kernel: SCSI subsystem driver Revision: 1.00 May 21 12:21:10 ficus2 kernel: (scsi0) found at PCI 0/13/0 May 21 12:21:10 ficus2 kernel: (scsi0) Narrow Channel, SCSI ID=7, 16/255 SCBs May 21 12:21:10 ficus2 kernel: (scsi0) Cables present (Int-50 YES, Ext-50 NO) May 21 12:21:10 ficus2 kernel: (scsi0) Downloading sequencer code... 436 instruc tions downloaded May 21 12:21:10 ficus2 kernel: scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-F ast SCSI) 5.2.4/5.2.0 May 21 12:21:10 ficus2 kernel: ======================================================================== the SCSI disk is listed, but then I see (copied from the screen) scsi: aborting command due to timeout ... repeated for various scsi IDs and the a never(?) ending cycle of ... SCSI host0 abort, timed out - resetting ... time out - trying harder ... The following didn't help: o driver aic7xxx_old o kernel patch linux-aic7xxx-6.2.5-2.4.18.patch With the patch, the error messages look more specific. I would have to copy them from the screen... But with kernel boot options "noapic" or "nosmp" the new driver works! (both with and without the patch.) There was no such problem with aic7xxx in 2.2.x-SMP kernels. Hardware: S1662D dual PPro motherboard (440FX) Adaptec AHA-2940UW SCSI adapter 9GB SCSI disk, QUANTUM ATLAS_V__9_WLS Rev: 0230 Booting with "noapic" is a workaround for me, and the hardware is old anyway. If, however, someone needs more info for debugging, please let me know. (I'm not subscribed to linux-scsi.)
