怎么会这样 Fast Data Access MMU Miss

zgccpy

非常感谢大家的帮忙，即使搞不好也高兴

我见过有一台CDROM太老，CD太新就出现过这样的错误。尽量试试boot net -s看看。

zgccpy

使用 set-defaults，依然如故，今天换光驱试试

非常感谢大家的热情帮助，更换光驱后问题解决

我也遇过这种提示。当时有CPU CACHE方面的出错提示。后来换CPU后就好了。

我在安装一台4800的时候也碰到这个问题，用2222A接D240的时候有BUG，BUG ID是4727426，以后大家注意一下！

This problem is on the Cauldron (X2222A) pci card connected to a D240
on a Sun Fire (Serengeti) machine.

Problem: When a probe-scsi-all command is issued at the OBP level of a
         domain,
         a) the command does not display the entire path to the
            devices connected to it.
         b) issuing a boot command immediately fails.
            A reset or reset-all is required.
            

The probe-scsi-all output does not show the entire path to the
devices connected to a cauldron pci card.

  
{10} ok probe-scsi-all
/ssm@0,0/pci@1d,600000/SUNW,qlc@1
/ssm@0,0/pci@1d,700000/scsi@2,1
/ssm@0,0/pci@1d,700000/scsi@2
/ssm@0,0/pci@1c,600000/pci@1/scsi@2,1
/ssm@0,0/pci@1c,600000/pci@1/scsi@2    <<<<this is incomplete path
Target 0
  Unit 0   Disk     FUJITSU MAJ3182M SUN18G 0804
Target 3
  Unit 0   Processor             2   
Target 6
  Unit 0   Removable Read Only device    TOSHIBA DVD-ROM SD-M14011007

The following scenarios has happen in the Field resulting
in not able to boot

1. using incomplete boot path
  ok>; boot  /ssm@0,0/pci@1c,600000/pci@1/scsi@2
  ERROR: Can't open boot-device
  
2. using complete boot path to DVDrom

  ok>;boot /ssm@0,0/pci@1c,600000/pci@1/scsi@2,0/disk@6,0:f
  ERROR: Fast Data Access MMU Miss


It appears that a boot command is issued right after the probe-scsi-all command,

the boot comamnd will fail with Can't open boot-device,  Fast Data Access MMU
Miss. This has been tested on system controller firmware 5.12.6 and 5.13.2

When a reset or reset-all command is issued, booting off the Cauldron (X2222A)
card is successful.
