Component:  Installer                     |    Version:  9.1-RELEASE
 Keywords:  kernel panic on 9.1 USB-live  |
------------------------------------------+-------------------------
 Booting PCBSD9.1-RELEASE-x64-USB-live-latest.img results in kernel panics
 on both Lenovo X1 Carbon and Dell Optiplex 755.  FreeBSD 9.1-RELEASE-
 amd64-memstick.img boots correctly on the Lenovo, so I'll file this as a
 PC-BSD bug.

 The downloaded .bz2 md5sum is correct: MD5
 (PCBSD9.1-RELEASE-p15-07-19-2013-x64-USB-live.img.bz2)=
 6d7880e4d2916c603f3968d736fbd229.  The unzipped size = 5930573824.  I
 wrote the image to two different USB sticks (one 8G, one 32G), both using
 dd on a FreeBSD 8.2 host.

 The Lenovo X1 is running Windows7. Setting BIOS to Legacy and disabling
 USB 3.0 didn't help. The Dell is running some recent Linux.

 Since it's a kernel panic on boot, there's no sysinstall log, etc.
 Actually, I don't know how to sensibly capture a kernel panic on an
 installer. (Setting dumpdev to swap wouldn't work, nor would remote gdb,
 esp. if the problem is in USB drivers...)  The Dell pauses and shows the
 kdb_backtrace, but the Lenovo doesn't.  I took video of the screen and
 stepped through it to capture the panics.

 Dell Optiplex 755: Current process = 15 (usbus2); trap number = 12; panic:
 page fault.  The relevant bit of the stack trace seems to be
 if_alloc+0x71; zyd_attach+0x1ba; device_attach+0x72;
 usb_probe_and_attach+0x1f9.

 Lenovo X1 Carbon: Current process = 15 (cdce0); trap number = 12; panic:
 page fault.  The relevant bit of the stack trace seems to be
 if_alloc+0x71; ue_attach_post_task+0x9a; usb_process+0xd3.

 I can make the video available (files are large) and am willing to spend a
 little time on this before defaulting back to FreeBSD install.  (The Dell
 isn't my machine, I just used it briefly to try to isolate the problem, so
 I can't debug further there.)
