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!
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...
