Thanks for the info. So do I understand correctly that after:

commit 6aa65472d18703064898eefb5eb58f7ecd0d8912
Author: Michael Buesch < XXXX@XXXXX.COM >
Date: Mon Jun 26 00:25:30 2006 -0700

[PATCH] CAPI crash / race condition

you were actually still seeing LIST_POISON2 Oopses in
capiminor_del_ack(), but after:

commit 053b47ff249b9e0a634dae807f81465205e7c228
Author: Michael Buesch < XXXX@XXXXX.COM >
Date: Mon Feb 12 00:53:26 2007 -0800

[PATCH] Workaround CAPI subsystem locking issue

they were gone? That's interesting. I'll try to wrap my mind around
this. capiminor_del_ack() isn't that big, after all.

It's unfortunate that these crashes only seem to occur with one specific
device (FritzCard DSL) which I don't have. Can anyone shed some light on
what that device is doing differently from other ISDN cards?

Thanks,
Tilman
