A regression.. Begin forwarded message: Date: Sun, 21 May 2006 10:34:50 -0700 From: bugme-daemon@xxxxxxxxxxxxxxxxxxx To: bugme-new@xxxxxxxxxxxxxx Subject: [Bugme-new] [Bug 6593] New: Plextor CDR PX-W4012 and kernel > 2.6.13 http://bugzilla.kernel.org/show_bug.cgi?id=6593 Summary: Plextor CDR PX-W4012 and kernel > 2.6.13 Kernel Version: 2.6.14 and higher version Status: NEW Severity: normal Owner: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx Submitter: nkieffer@xxxxxxxxx Most recent kernel where this bug did not occur: vanilla 2.6.17-rc4 Distribution: Gentoo Hardware Environment: Adaptec SCSI Card 29160, MSI K7-Master Motherboard Software Environment: kernel 2.6.14 and higher Problem Description: When I upgraded the kernel from Vanilla 2.6.13.4 to 2.6.14.x and higher, the plextor CDR PX-W4012 (SCSI ID 3) is encountering errors when inserting and mounting a CD. The scsi channel is then restarted again and again. The weird thing is the Plextor SCSI CD-ROM PX-40TS reader is not impacted by this issue. So it does only impact some specific drives. I do not think it is related to this bug : http://bugzilla.kernel.org/show_bug.cgi?id=5659 Using older kernel (<2.6.14 series) do not show this issue ! I even tried latest gentoo kernel available and the same problem occur, whereas the gentoo 2.6.16r7 almost permit to access to CD between 2 channel reset. --------------DMESG----------------------------------------------------------- ACPI: PCI Interrupt 0000:00:09.0[A] -> GSI 17 (level, low) -> IRQ 17 scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 <Adaptec 29160 Ultra160 SCSI adapter> aic7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs Vendor: QUANTUM Model: ATLAS10K2-TY184L Rev: DDD6 Type: Direct-Access ANSI SCSI revision: 03 scsi0:A:0:0: Tagged Queuing enabled.
