call doadump doesn't work?

[Will Andrews]

Hi,

I am trying to fix the ti(4) driver for sparc64 (among others).
But while probing the NIC, the kernel panics, and I am unable to
get a dump:

[...]
ti0: <Alteon AceNIC 1000baseSX Gigabit Ethernet> mem 0x3004000-0x3007fff at device 1.0 on pci1
ti0: unsupported chip revision
ti0: chip initialization failed
panic: trap: fast data access mmu miss
cpuid = 0; 
Debugger("panic")
Stopped at      Debugger+0x1c:  ta              %xcc, 1
db> call doadump
Dumping 640 MB (2 chunks)

And it stays there.  I left this running overnight.  I must be
missing something... isn't doadump() supposed to work on sparc64
(there's a src/sys/sparc64/sparc64/dump_machdep:dumpsys())?
This is with dumpdev="/dev/ad0b" and dumpdir="/usr/crash" in
rc.conf.

TIA.

Regards,
