Heyyo,
The last time you tuned in, we were having fun with getting a drive
partitioned so that I could shed the abysmal NFS performance.
Well,
Now, it hangs upon bootup. During bootup off of the drive, it (the kernel)
detects vmel0 and vmes0 and stops. Normally, it should be mounting root
at this point.
I compiled in a kernel using DIAGNOSTIC, DDB, and DEBUG, and booting it up
gives me:
[...standard kernel messages...]
vmel0 at mainbus0
vmes0 at mainbus0
Process (pid 1) got signal 11
Process (pid 1) got signal 11
Process (pid 1) got signal 11
[...repeat, 9600baud...]
/usr/include/sys/signal.h shows 11 as:
#define SIGSEGV 11 /* segmentation violation */
Anyone know what's going on here, and what the fix is?
I can consistently boot just fine over the wire, but never off of the drive.
Some machine properties:
20M, jumpers for mem set properly (passes full diag test)
one drive, set to scsi id 0 (prom likes it there, calls it sd(0,0,0))
prom -will not- boot off of the drive if it is set to scsi id 3
serial console, p4-bwtwo on system board but not used.
fully populated /dev (checked and verified twice)

# NCR5380-based "Sun SCSI 3" VME SCSI controller.
# This driver has several flags which may be enabled by OR'ing

# Valid flags are:
#
# 0x01 Use DMA (may be polled)
# 0x02 Use DMA completion interrupts
# 0x04 Allow disconnect/reselect
#
# E.g. the following would enable DMA, interrupts, and reselect:
# si0 at vmes0 addr 0xff200000 level 3 vect 0x40 flags 0x07
#
# By default, DMA is enabled in the driver.
