Subject: Re: bug in tty ldisc and friends

Message-ID: <20090616100015.GD6432@elte.hu> (raw)

got the debug data off-list (it's large):

 lock-classes:                         1763 [max: 8191]
 direct dependencies:                  9104 [max: 16384]
 indirect dependencies:              129622
 all direct dependencies:           1129624
 dependency chains:                    9781 [max: 32768]
 dependency chain hlocks:             27553 [max: 163840]
 in-hardirq chains:                    1573
 in-softirq chains:                     131
 in-process chains:                    8077
 stack-trace entries:                262144 [max: 262144]

stack-trace entries ran out. And it seems like you didnt quadruple 
MAX_STACK_TRACE_ENTRIES to 1 million entries.

Do we run out of entries right during bootup? Are you 
loading/unloading modules a lot perhaps? Could you send your .config 
please? (assuming a plain bootup triggers it - that should make it 
reproducible to me too)

Thanks,

	Ingo
