Hello,
I have managed to lock my (amd64, RELENG_7) machine up twice today. In
both cases, I was transferring a file to my laptop (in one case over
SMB, the other over FTP). Both resulted in a hard lock (no panic). One
of the lockups had an "em1: watchdog timeout" message on the console,
the other had no abnormal messages on the console. Both transfers were
over 100baseTx-FD ethernet over my em card (em1).
This is a new occurrence on RELENG_7. The box was stable on
6.2-RELEASE. The hardware is as follows:
Asus P5B motherboard (BIOS revison 1405)
Intel Core 2 Quad Q6600
Two Intel em cards (em0: internet facing, em1: LAN facing)
Further below is my full kernel config, but here are the options I
have that GENERIC does not (not necessarily in order, as they were
sorted when I was diff'ing with GENERIC):
device atapicam
device coretemp
device if_bridge
device pf
device pflog
device tap
ident PFLOG64
machine amd64
makeoptions COPTFLAGS="-O2 -pipe"
options ALTQ
options ALTQ_CBQ
options ALTQ_HFSC
options ALTQ_NOPCC
options ALTQ_PRIQ
options ALTQ_RED
options ALTQ_RIO
options COMPAT_LINUX32
options HZ=1000
options LIBICONV
options LIBMCHAIN
options NETSMB
options SC_PIXEL_MODE
options SMBFS
options UDF
options VGA_WIDTH90
I plan on removing the HZ, LIBICONV, LIBMCHAIN, SC_PIXEL_MODE, and
VGA_WIDTH90 options and seeing if that helps. Do any of the other
options look like likely culprits?
If the above doesn't help, is there a way to debug hard lockups? I
have 15mbit FiOS and have maxed em0 out without causing this. So I'm
guessing either I'm not pushing enough packets through em0 to induce
this, or the problem is related to em1 sharing an interrupt with a USB
controller:
interrupt total rate
irq1: atkbd0 6 0
irq6: fdc0 10 0
irq17: uhci1+ 91 0
irq19: uhci3+ 924492 32
irq22: em0 85919 3
irq23: em1 uhci2+ 6627 0
cpu0: timer 56950868 1999
cpu1: timer 56950834 1999
cpu2: timer 56950835 1999
cpu3: timer 56950834 1999
Total 228820516 8035
Anyway, here is the full kernel configuration:
makeoptions COPTFLAGS="-O2 -pipe"
machine amd64
cpu HAMMER
ident PFLOG64
options COMPAT_IA32
options COMPAT_LINUX32
