Description of problem:
The hisax isdn driver is supposed to support the Sedlbauer fax  pci isdn card. This card is semi-active and supports send and receive 
faxes. With kernel RPM 2.4.2, the original kernel shipped with RH LInux 7.1, it works. With kernel 2.4.9-12 from the latest update, it fails 
with the message in /var/log/messages:

isar recmsg IRQSTA timeout
isar waitrecmsg prog failed

The AT emulator /dev/ttyI* will then not accept fax commands (AT FCLASS fails).


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Take a fresh RedHat 7.1 installation with a Sedlbauer speed fax  PCI card. isdn4k-utils must be installed.
2. Load driver kernel module: insmod hisax type=28
3. Load firmware: /usr/sbin/hisaxctrl HiSax 9 /usr/lib/isdn/ISAR.BIN
4. Use minicom or cu to connect to /dev/ttyI0
5. Enter at fclass=?

The problem is confirmed by one of the isdn4linux maintainers at the URL given above. The page also contains a small patch which is 
supposed to fix the problem. I haven't tried it myself so far, though
