I made it happen again by doing the same installworld but this time I caught it in the debugger. I'll leave the machine up for a while in case someone has some idea of how to debug it. The stacktrace looks like this: #0 Debugger () at ../../alpha/alpha/db_interface.c:260 #1 0xfffffc000036c2c0 in panic () at ../../kern/kern_shutdown.c:444 #2 0xfffffc00004942fc in vm_page_alloc () at ../../vm/vm_page.c:1041 #3 0xfffffc00003a1b54 in allocbuf () at ../../kern/vfs_bio.c:1791 #4 0xfffffc00003a13d4 in getblk () at ../../kern/vfs_bio.c:1572 #5 0xfffffc000046a150 in ffs_balloc () at ../../ufs/ffs/ffs_balloc.c:170 #6 0xfffffc00004772dc in ffs_write () at vnode_if.h:1015 #7 0xfffffc00003b3c00 in vn_write () at vnode_if.h:331 #8 0xfffffc000037f72c in write () at ../../kern/sys_generic.c:270 #9 0xfffffc00004b0a4c in syscall () at ../../alpha/alpha/trap.c:620 #10 0xfffffc00004a416c in XentSys () at ../../alpha/alpha/exception.s:127 -- Doug Rabson Mail: d...@nlsystems.com Nonlinear Systems Ltd.
