Package: sl-modem-source
Version: 2.9.9a-1
Severity: wishlist
Some of the ALI chipset modems supported by this driver are detected by
the Linux kernel on boot and identified as modems. Their PCI address is
then assigned to the default serial driver intended for real modems.
Up until the 2.6.10 driver, there was a workaround allowing the serial
driver to be released in such cases; starting with 2.6.10, there is no
such workaround. When the slmodem driver is to be loaded, it finds the
hardware is already taken and refuses to load:
slamr: device 10b9:5457 is grabbed by another driver
This behavior requires a simple fix in the 8250_pci.c serial driver in
the kernel, along the lines below -- the patch is said to be from Sasha
Khapyorsky <[EMAIL PROTECTED]>, the upstream author of the driver, and
was sent to me by Jacques Goldberg on the linmodems.org discussion list.
Tested on my system and solves the problem.
As this is not a bug in the sl-modem driver, I'm unsure how best to file
the bug and the proposed patch; please feel free to forward it to the
Debian kernel patcher if that seems appropriate to you; at some point it
should go to the mainline kernel. In the meantime it might help people
here who run into this problem. The diff is against the latest 2.6.10-6
Debian kernel source.
