Subject: [3.11-rc5..] NULL pointer dereference,
lockup after XHCI device dropped out
Hi,
I hit a BUG followed by a lockup when trying to wipe a new external USB 3.0
1TB 2.5" "Western Digital My Passport" (WDBBEP0010BBK-EESN) HDD.
The following command is used (with sudo):
dd if=/dev/zero of=/dev/sdd bs=1M
In another shell, I kept sending a USR1 signal to watch progress (maybe
not related, but mentioned for completeness):
while killall -USR1 dd; do sleep 30; done
While doing this over SSH, another KDE session was open with someone
playing the Java game Minecraft.
I have so far reproduced this lockup three times. The first time, the
lock-up occured after:
84838+0 records in
84838+0 records out
88959090688 bytes (89 GB) copied, 789.707 s, 113 MB/s
I have no logs from the first lockup. The second time (after a reboot):
388514+1 records in
388514+1 records out
407386685440 bytes (407 GB) copied, 3881.25 s, 105 MB/s
The second log part (not "third lockup log") below is from this session.
I omitted the remaining lines that are printed when the CPU got hung.
The third BUG occured 22 minutes (156 GB) after rebooting and running
dd and has similar log entries to the previous lock-up. This kernel used
the same kernel sources, but with XHCI debugging enabled. No
differences were noticable in the console output, other than the missing
"xHCI xhci_drop_endpoint called with disabled ep" message in the new
logs. See the first console output below.
I have no idea why the USB 3.0 HDD would drop out, but that should
not trigger a NULL pointer dereference anyhow.
The desktop was running kernel v3.11-rc5-35-gf1d6e17 plus three r8169
patches that are unrelated to this issue and has 24 GB RAM and a i5-2320
CPU. I do not know how to easily reproduce this bug, the current
"reproduction" method described above takes time.
One possibly related bug is https://bugzilla.kernel.org/show_bug.cgi?id=51641,
but I do not have a panic. Any ideas? If you want me to test something
or open a new bug, let me know.
Regards,
Peter
