System : OpenBSD 4.2
Details : OpenBSD 4.2-current (GENERIC) #0: Sun Dec 9
12:26:33 PST 2007
root@feynman:/usr/src/sys/arch/i386/compile/GENERIC
Architecture: OpenBSD.i386
Machine : i386
>Description:
Creating a bootable block device using a USB flash device
generates the following panic:
uvm_fault (0xd06fc920,0x0,0,1) -> e
fatal page fault (6) in supervisor mode
trap type 6 in code 0 eip d02d0acf cs 8 eflags 10297 cr2 0 cpl 0
panic: trap type 6, code=0, pc=d02d0acf
syncing disks... done
dumping to dev 1101, offset 0
dump error 19
rebooting...
Creating a bootable device with the same USB flash drive with
the March 25 snapshot of -current
works fine.
>How-To-Repeat:
The hardware specifics of the Corsair USB drive can be found
in the dmesg(8) output below.
