It looks like real bad news for the Alpha. :-( I built and
installed the kernel as instructed, and then started a make
buildworld. That died soon with this:
===> usr.bin
"/a/src/usr.bin/Makefile", line 223: Unclosed conditional/for loop
"/a/src/usr.bin/Makefile", line 223: Unclosed conditional/for loop
"/a/src/usr.bin/Makefile", line 223: 1 open conditional
"/a/src/usr.bin/Makefile", line 223: 1 open conditional
make: fatal errors encountered -- cannot continue
make: fatal errors encountered -- cannot continue
*** Error code 1
*** Error code 1
I suspect it's caused by the trailing backslash in the "doscmd" line
near the end:
.if ${MACHINE_ARCH} == "i386"
# Things that don't compile on alpha or are aout specific:
SUBDIR+=ar \
brandelf \
gcore \
gprof4 \
nm \
ranlib \
sasc \
size \
strings \
strip
# doscmd \
.endif
Anyway, when the make buildworld failed, I tried to do a "cvs
status" or some such thing, which caused amd to attempt to mount the
repository from a different machine. Wham, instant panic, and it
trashed out one of my filesystems _thoroughly_ -- 1000 files and 10
MB in lost+found. :-(
Once I got things patched up again with a little chewing gum, I was
able to get a core dump. It overflowed the kernel stack with
zillions of recursive calls to nfs_sigintr:
#37 0xfffffc0000409404 in nfs_sigintr (nmp=0x0, rep=0x0, p=0x0)

#44 0xfffffc0000409404 in nfs_sigintr (nmp=0x0, rep=0x0, p=0x0)

I haven't found the bottom of the stack yet (11000 frames and
counting ...). Let me know if you'd like some additional info.
