Bug #2291: Panic in lwkt_remove_tdallq
http://bugs.dragonflybsd.org/issues/2291

Author: Rumko Rumko
Status: Closed
Priority: Normal
Assignee: 
Category: 
Target version: 


With a few days old master and under some I/O load I get the mentioned panic (the actual panic message is illegable, only the trace can be read) ... was unable to get a core dump (panic in ddb didn't produce a dump, only rebooted the machine). The panic seems to be easily repeatable (unfortunately this is the first time I actually saw a trace, because I had DDB_UNATTENDED switched on before + was in X, so could not see the message)

Part of the backtrace (only the function names, I managed to take pictures of the backtrace itself, attached to this report):
panic()
lwkt_remove_tdallq()
free_lock()
acquire_lock()
softdep_disk_io_initiation()
devfs_spec_strategy()
vop_strategy()
vn_strategy()
ufs_strategy()
ufs_vnoperate()
vop_strategy()
vn_strategy()
bawrite()
...
syncer_thread()
syncer_thread_start()
kthread_exit()
