[mdb-discuss] spurious mdb stops in sigacthandler when debugging b117 Xorg ?

2009-07-05 Thread Jürgen Keil
I'm trying to debug an Xorg mouse problem in b116 or newer, on 32-bit x86. The problem is that under unknown conditions the mouse pointer jumps to the upper left screen corner. ( http://www.opensolaris.org/jive/thread.jspa?threadID=105715tstart=0 ) Unfortunately, when I recompile Xorg from

[mdb-discuss] kmdb amd64: parameters not shown in stack backtraces ?

2008-10-15 Thread Jürgen Keil
I'm not exactly sure when it happened (somewhere between snv_98 and snv_100), but starting a couple of weeks ago kmdb appears to have lost the ability to display parameter values in stack backtraces on the amd64 platform. E.g. on an old build 82 or wiith an opensolaris snv_97 livecd, mdb -k /

[mdb-discuss] mdb wraps lines at 80 characters when input is redirected

[mdb-discuss] mdb :r command corrupts arguments for 64 bit x86 debug target

2010-02-06 Thread Jürgen Keil
Can anyone reproduce this: I'm running SX:CE b129 amd64, bfu'ed to current ON bits; the same problem exists on OpenSolaris dev build b132. I'm trying to debug a /usr/sbin/amd64/update_drv problem, using mdb. Problem is that the debug target somehow receives a :r quoted string argument slightly
