npcfs crashes if copy job netware 5.1 mounted volume via ncpmount tcp or ipx is done

English Network/Internet
1

After update 11.2 to 11.4 copy jobs from netware 5.1 volume to local disk linux system does crash after a couple of seconds. I might have to do if there a allot of small files in that job. If happend system reboot is required because unmount netware volume nor delete copied files to the local linux system is not possible.

Recompiling ncpfs package not possible because error free source package ncpfs version 2.2.6 might not be availble.

Yes, it is unfortunate, bugzilla reports are almost not solved nowdays.
Perhaps they are understaffed. :frowning:

But it is a kernel bug, they have to be reported, and they are the only
people capable to correct those. Be patient… for some bugs I had to wait
years.
