hi,

just got above panic while fsck'ing after an reboot: 
(this an ss20 running currend supped this morning)

data fault: \
     pc=0xf003d954 addr=0xfc017000 sfsr=3a6<PERR=0,LVL=3,AT=5,FT=1,FAV,OW>

here's the db-trace:
_mem_access_fault4m
_memfault_sun4m
_mi_switch
_extent_alloc_region_descriptor
_extent_free
_iommu_dmamap_unload
_lsi64854_scsi_intr
_esp_dma_intr
_ncr53c9x_intr
_sparc_interrupt44c
_mi_switch
_tsleep
_physio
_sdread
_spec_read
_ufsspec_read
_vn_read
_dofileread
_sys_read
_syscall
syscall

hmm... both the disks on the internal esp and the two externals on the
isp are fsck'ed. could be they are "stepping on each others feet"?
or says mem_access_fault4m that there can be a bad simm somewhere???
resetting and restarting the beast brings it up again (most of the
time ;-).

any clues someone?

thanks,

-ks
