In a 4.4-STABLE snapshot of mid-december I experience new ISDN related
problems:
a) When starting "/usr/sbin/isdnd -dn -d0x1f9 -f"
(maybe triggered by restarting it interactively with key '6'?), I
observe a load of zombie processes belonging to isdnd:

b) After a fresh start of isdnd connections work fine, but after a while
I see this in the syslog files:
i4b-L1 isic_isac_irq: unit 0: CRC error
i4b-L1 isic_isac_irq: unit 0: CRC error

IIRC I did not have these problems with 4.3-STABLE. Yes I checked the
cable (even replaced it), and a freshly started isdnd seems to work
okay.
Also, I sometimes see this (alas, I cannot make much out of it):

I am working with both kernel-ippp and rbch-userPPP-tun0.
What other info can I supply to track this down? I am currently building
4.5-PRERELEASE and will retry with it.
Helpless,
Martin
