Hmmmm...well, it sure would be nice if SiS would use the public sis190 driver instead of having their own completely different driver by the same name... :-( This may take a while to ferret-out the relevant differences...I'll see what I can do. Sent email to Chung-Hsien Chang <changch> asking for whatever help he might provide with this issue. ...and the email bounced...grrr... Have I got an Email bounced or Mr. Chung-Hsien Chang? I have tryed the new kernel, but the driver for [sis190] in the kernel-2.6.14-1.1656_FC4 is the same as in kernel-2.6.14-1.1653_FC4, and the problem is still valid. Created attachment 122924 [details]
Proposed patch to [sis190.c]
Just a [diff -Nup] between the original kernel driver and SiS driver.
(Chang's email bounced...) As you can tell from the diff, the two drivers basically only share the same name. They don't appear to be related at all. If they were more similar, it might be easy to pick-out a few changes from the diff. As it is, it will take someone with better knowledge of the drivers and/or hardware, or at least more research. Gustavo, I have a question, and something for you to try. My question is: what happens if you boot to single user mode, and load the stock module (from kernel-2.6.14-1.1653_FC4) by hand (i.e. running modprobe sis190)? Does the system still hang? If not, what actually happens? Also, when trying this experiment, try to pass the command line argument debug=16 when you probe it; that will give more debugging information. Thanks, Chris Christopher, I have done what you asked but now it is working and I do not know why. I tryed to figure it out, why now it works, but I could not. What I can say about the problem is that it was never about loading the driver but trying to bring it up. What you instructed me I had done before I issue this bug (but without the parameter debug=16) and everything went good until I tryed to bring the interface up (by using "ifup" and "ifconfig") then it hangs. But now it is ok and I'm sorry that I can no longer reproduce the problem. Thanks anyway. 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. This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. Thank you. The problem was resolved by the new kernel: 2.6.15-1.1830_FC4. |
