https://bugzilla.suse.com/show_bug.cgi?id=1213537 Bug ID: 1213537 Summary: myrb / myrs drivers cause hang on boot when using a Mylex AcceleRAID 170 (DAC960) Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: x86-64 OS: openSUSE Leap 15.5 Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: medwards-suse@mirkwood.net QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 868350 --> https://bugzilla.suse.com/attachment.cgi?id=868350&action=edit dmesg Booting opensuse leap 15.5 fails on this machine - shortly after the myrb and myrs drivers load and detect the AcceleRAID 170 and drives connected to this card, booting simply stops. Waiting for a few minutes will let me see kernel warnings about hung processes, but booting never completes at this point. Adding modprobe.blacklist=myrb and modprobe.blacklist=myrs to the kernel commandline lets boot complete, though obviously without the AcceleRAID card in use. Once booted, I was able to enable dyndbg for these two drivers: # for d in myr{s,b}; do echo 'file drivers/scsi/${d}.c +p' > /sys/kernel/debug/dynamic_debug/control; done Loading the drivers manually caused the modprobe for myrs to hang (myrb loaded w/o issue), leading me to believe the problem lies within the myrs driver. dyndbg of myrb + myrs: drivers/scsi/myrs.c:2114 [myrs]myrs_monitor =_ "monitor tick\012" drivers/scsi/myrs.c:1822 [myrs]myrs_slave_alloc =_ "Logical device mapping %d:%d:%d -> %d\012" drivers/scsi/myrs.c:471 [myrs]myrs_get_fwstatus =_ "Sending GetHealthStatus\012" drivers/scsi/myrs.c:338 [myrs]myrs_get_pdev_info =_ "Sending GetPhysicalDeviceInfoValid for pdev %d:%d:%d\012" drivers/scsi/myrs.c:249 [myrs]myrs_get_ldev_info =_ "Sending GetLogicalDeviceInfoValid for ldev %d\012" drivers/scsi/myrs.c:189 [myrs]myrs_get_ctlr_info =_ "Sending GetControllerInfo\012" drivers/scsi/myrb.c:2445 [myrb]myrb_monitor =_ "reschedule monitor\012" drivers/scsi/myrb.c:2436 [myrb]myrb_monitor =_ "new enquiry\012" drivers/scsi/myrb.c:2432 [myrb]myrb_monitor =_ "get background init status\012" drivers/scsi/myrb.c:2427 [myrb]myrb_monitor =_ "get consistency check progress\012" drivers/scsi/myrb.c:2421 [myrb]myrb_monitor =_ "get rebuild progress\012" drivers/scsi/myrb.c:2415 [myrb]myrb_monitor =_ "get logical drive info\012" drivers/scsi/myrb.c:2409 [myrb]myrb_monitor =_ "get rebuild progress\012" drivers/scsi/myrb.c:2403 [myrb]myrb_monitor =_ "get error table\012" drivers/scsi/myrb.c:2397 [myrb]myrb_monitor =_ "get event log no %d/%d\012" drivers/scsi/myrb.c:2390 [myrb]myrb_monitor =_ "monitor tick\012" drivers/scsi/myrb.c:2360 [myrb]myrb_handle_scsi =_ "Device nonresponsive\012" drivers/scsi/myrb.c:2355 [myrb]myrb_handle_scsi =_ "Attempt to Access Beyond End of Logical Drive" drivers/scsi/myrb.c:2350 [myrb]myrb_handle_scsi =_ "Logical Drive Nonexistent or Offline" drivers/scsi/myrb.c:2331 [myrb]myrb_handle_scsi =_ "Bad Data Encountered\012" drivers/scsi/myrb.c:1699 [myrb]myrb_pdev_slave_alloc =_ "slave alloc pdev %d:%d state %x\012" drivers/scsi/myrb.c:1693 [myrb]myrb_pdev_slave_alloc =_ "device not present, skip\012" drivers/scsi/myrb.c:1687 [myrb]myrb_pdev_slave_alloc =_ "Failed to get device state, status %x\012" drivers/scsi/myrb.c:1639 [myrb]myrb_ldev_slave_alloc =_ "slave alloc ldev %d state %x\012" drivers/scsi/myrb.c:1438 [myrb]myrb_ldev_queuecommand =_ "ldev %u in state %x, skip\012" drivers/scsi/myrb.c:1414 [myrb]myrb_read_capacity =_ "Capacity %u, blocksize %u\012" See attachment for dmesg output. myrs was loaded around timestamp 16372.039529. -- You are receiving this mail because: You are on the CC list for the bug.
