To: linux-support [blah] smlink.com Hi, I tried to manually unload the slamrkernel driver on 2.6.24.2 and I got a kernel crash (see the attachmemnt). Hope this helps you to fix the problem. I use Gentoo linux, so the "-r1" comes from that. I wonder whether the currently deprecated pci_find_device() which I have disabled in my kernel could have caused that. Please note the following in the compile output below: <quote> make[1]: Entering directory `/usr/src/linux-2.6.24.2' CC [M] /var/tmp/portage/net-dialup/slmodem-2.9.11_pre20080126-r1/work/ungrab-winmodem-2.9.11-20080126/ungrab-winmodem.o /var/tmp/portage/net-dialup/slmodem-2.9.11_pre20080126-r1/work/ungrab-winmodem-2.9.11-20080126/ungrab-winmodem.c: In function ‘softmodem_release_init’: /var/tmp/portage/net-dialup/slmodem-2.9.11_pre20080126-r1/work/ungrab-winmodem-2.9.11-20080126/ungrab-winmodem.c:83: warning: ‘pci_find_device’ is deprecated (declared at include/linux/pci.h:492) </quote> Please let me know what do you think. many thanks, Martin # emerge slmodem Calculating dependencies... done! >>> Verifying ebuild Manifests... >>> Emerging (1 of 1) net-dialup/slmodem-2.9.11_pre20080126-r1 to / * slmodem-2.9.11-20080126.tar.gz RMD160 SHA1 SHA256 size ;-) ...

So, does it work w/ CONFIG_PCI_LEGACY enabled? You really shouldn't disable something in kernel just because someone thought marking it as 'legacy' is a wonderful idea.
Created attachment 145257 [details] /proc/config Actually, I do have it enabled though I thought I don't. ;-) CONFIG_PCI_LEGACY=y
Check if slmodem-2.9.11-20080401 fixed your problem.
Yes, it does not complain about pci_find_device() against 2.6.24.3. Thanks.
Question is, does your kernel still crashes when you unload slamr?

I cannot reproduce this crash. Maybe a decent cleanup is still necessary: # modprobe slamr WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.

In version slmodem-2.9.11_pre20090222-r1, I've fixed the modprobe warning about /etc/modprobe.d/slmodem file. Closed as FIXED... finally :)
