What exact revision? Trunk or alpha2 branch?

Do you have syslog debug output disabled?

Replying to HaikuBot:

hrev36530. Yes, disabled.

And trunk.

Any other non-default kernel settings?

This looks very similar to, which should be fixed in hrev36528. At least I could reproduce the KDL entering double fault before and can't anymore.

If you haven't changed/rebuilt this Haiku installation, please run

objdump -D --demangle /system/kernel_x86 | grep -C 100 800d2f77 > ~/Desktop/double-fault-eip.txt

in the Terminal and attach the generated file (double-fault-eip.txt on the desktop).

In the same situation I fall through sometime into KDL. To reproduce the problem at 100% I do the following:

1) Open Applications folder;

2) Press Ctrl-A to Select All links to applications;

3) Select "Open" from context menu;

4) After some seconds opening all applications - the KDL debugger welcomes me. The backtrace always say about CDPlayer process.

Screenshot is attached.

Maybe this is the same problem?

Looks like the 6 byte emulation code in the SCSI bus manager is broken.

comment:9 by bonefish, 10 years ago

Resolution: fixed
Status: in-progressclosed

The problem with the not correctly balanced lock_memory() call is fixed in hrev36539. HaikuBot, if you still get a double fault when entering KDL (e.g. via Alt-Sysreq-D), please open a new ticket.
