Boot with kernel-2.6.13-1.1526_FC4 2. Observe modem not working 3. Boot with kernel-2.6.12-1.1456_FC4 and earlier 4. Observe modem working Additional info:
2.6.14-1.1637_FC4 has been released as an update for FC4. Please retest with this update, as a large amount of code has been changed in this release, which may have fixed your problem. Thank you.
Unfortunately the problem still persists with the new kernel.
I'm seeing the exact same problem, I upgraded from FC3 to FC4 and everything worked. I used YUM and was upgraded from kernel 2.6.11-1.1369_FC4 to kernel 2.6.14-1.1644_FC4 then the modem stopped working. My modem is a USR Sportster internal 56K Faxmodem and the Motherboard is an MSI KM2M with an Athalon processor.
This is a mass-update to all currently open kernel bugs. A new kernel update has been released (Version: 2.6.15-1.1830_FC4) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem.
