The following reply was made to PR kern/114597; it has been noted by GNATS. From: Gavin Atkinson <gavin.atkinson@ury.york.ac.uk> To: bug-followup@freebsd.org Cc: Subject: Re: kern/114597: [hang] Date: Fri, 18 Apr 2008 15:07:52 +0100 Collecting together info from PR 88315 from same submitter so that all info is in one place from PRs 88315 and 93128: The system is a Siemens Primergy 470, dual PIII 450MHz. It has two Symbios/LSI 83C895 HBAs, one is onboard and the second is on a separate PCI card. The onboard HBA has LVD hard drives, the second only single ended devices are connected. During the boot process of FreeBSD 6.0 RC1 the machine hangs at the marked lines (the output was generated on a FBSD 5.3 STABLE 3) (PR 88315): primergy470# dmesg | grep sym sym0: <895> port 0x3000-0x30ff mem 0xf0200000-0xf0200fff,0xf0201000-0xf02010ff irq 23 at device 1.0 on pci2 sym0: Symbios NVRAM, ID 7, Fast-40, LVD, parity checking sym0: open drain IRQ line driver, using on-chip SRAM sym0: using LOAD/STORE-based firmware. sym1: <895> port 0x1800-0x18ff mem 0xf0101000-0xf0101fff,0xf0102000-0xf01020ff irq 17 at device 13.0 on pci0 sym1: Symbios NVRAM, ID 7, Fast-40, SE, parity checking sym1: open drain IRQ line driver, using on-chip SRAM sym1: using LOAD/STORE-based firmware. [^^^^^^^^^^^^^^^^^^^^^^^^^^ on FBSD 6.0RC1 it hangs here!] On 6.x it hangs at this position (PR 93128): (noperiph:sym0:0:-1:-1): SCSI BUS reset delivered. (noperiph:sym1:0:-1:-1): SCSI BUS reset delivered. (noperiph:sym1:0:-1:-1): SCSI BUS mode change from SE to SE. [ 5 minute hang here ] da0 at sym0 bus 0 target 0 lun 0 da0: <COMPAQ BD036735C8 B020> Fixed Direct Access SCSI-2 device da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da0: 34732MB (71132000 512 byte sectors: 255H 63S/T 4427C) [ then no more ] The machine showed the same symptoms with FreeBSD 5.3 RC2, but was fixed for 5.3 RC3. It also worked under 5.4, but 6.0 and 6.2 failed in the same way. 7.0 boots, but only in safe mode.
