System: NetBSD this 2.0G NetBSD 2.0G (THAT) #341: Mon Jul 26 21:42:06 EDT 2004 andrew@this:/usr/src/sys/arch/i386/compile/THAT i386
my ex0 (3Com 3c905C) wedges the system when put to heavy use, while
"normal usage" (ie, interactive and web traffic) does not. i tried to
transfer a large (for me, meaning 2-3 gigabytes) amount of data to
another machine via netcat and the machine (my laptop; the ex0 is on
the docking station) became unresponsive shortly thereafter.
THAT#341, built from 20040722 sources, is fine
THAT#342, built from 20040917 sources, wedges
THAT#343, built from 20040925 sources, wedges
THAT#344, built from 20040925 sources, wedges
the difference between builds 343 and 344 is a "make cleandir" in the
kernel build directory.
i've also tried my url0 interface with no problem, a couple of ep
interfaces (pcmcia cards) with no problem, and a cardbus ex (3Com
3c575B) which also wedges, so this problem seems particular to the ex
start a large data transfer and just wait. fwiw, i was doing this:
% cd /usr/pkgsrc
% tar czf packages | nc server 13246
10 drop to ddb
20 count to five
40 kernel prints "ex0: uplistptr was 0"
50 wait for wedge to happen again
60 goto 10
