Tty spoolers must have an open() hanging on the port or the flow control is gone when the last job is printed. Also various "bus error" panics related to tar -f /dev/rst8 seem to occur quite regularly now and didn't before. Nothing for sure has been determined yet, but a certain tar dump that we regularly have to do will panic as follows: vmunix: tar: vmunix: trap address 0x8, pid 6679, pc = f06f7e4, sr = 2204, stkfmt b, context 6 vmunix: Bus Error Reg 20 vmunix: data fault address 11131113 faultc 0 faultb 0 dfault 1 rw 1 size 0 fcode 5 vmunix: KERNEL MODE vmunix: page map 20000000 pmgrp ff vmunix: D0-D7 2000 2200 5 0 0 f0b9ef8 2000 f0b9ef8 vmunix: A0-A7 11131113 0 f09f59a f09f56e f0b9f48 f0b9f60 ffff9630 ffff9610 vmunix: Begin traceback...fp = ffff9630, sp = ffff9610 vmunix: Called from f06f652, fp=ffff9654, args=f0b9f60 2000 0 0 vmunix: Called from f06ed86, fp=ffff9688, args=1208 0 0 2000 vmunix: Called from f06f200, fp=ffff96b0, args=1208 3 0 0 vmunix: Called from f042322, fp=ffff96d8, args=1208 3 ffff96d4 3 vmunix: Called from f039f76, fp=ffff973c, args=ffff9738 3 f1f5f44 0 vmunix: Called from f038dcc, fp=ffff9768, args=efffc79 0 603 1a4 vmunix: Called from f038d4a, fp=ffff9780, args=efffc79 603 1b6 ffff97b4 vmunix: Called from f064614, fp=ffff97a8, args=ffff9a18 efffc3c 0 0 vmunix: Called from f004768, fp=efffbf8, args=5 2 2d 5 vmunix: End traceback... vmunix: panic: Bus error vmunix: syncing file systems...
