Description Need Real Name 2001-11-15 17:00:42 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.78 [de]C-CCK-MCD DT  (WinNT; U)

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=?
	

Actual Results:  
0,8
OK

(missing "1")

Expected Results:  
0,1,8
OK

("1" indicating fax class 1 operration)

Additional info:

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

Please apply the patch in the next kernel updates - thanks!

Comment 1 Arjan van de Ven 2001-11-15 17:05:49 UTC
Thanks for this report! The patch looks good so I've added it to the kernel tree
for if/when we're doing a new erratum. 
I'll close this as "fixed in rawhide" as the patch is in the tree and it should
appear in rawhide soon...
