| |
If I have the cs46xx driver compiled either as a module or into the kernel, then 2.4.0-test12-pre4 locks up when KDE 2.0 is started.
The problem with dummy.o in 2.4.0-test12-pre4 allowed me to find the possible source of this lock-up which I have been seeing recently (since test11-ac2) while starting up KDE 2.0.
This morning, I tried out 2.4.0-test12-pre4, and KDE 2.0 started up (and there was much rejoicing). Of course, I saw the error when I tried to make modules, but I thought could live without sound for one bootup.
Then I applied Mohammad A. Haque's small patch to linux/include/linux/module.h, recompiled , and the system froze again at the same spot ("Loading the panel") while starting up KDE 2.0.
I found that if I said N for the cs46xx sound driver, then I get a 2.4.0-test12-pre4 kernel that will run KDE 2.0, sans sound :(.
I can run GNOME with 2.4.0-test12-pre4 with cs46xx compiled as a module or compiled into the kernel, and everything works just fine.
Here is some additional information from /var/log/messages: 2.4.0-test10 works OK with KDE 2.0 and sound.
For 2.4.0-test12-pre4:
Crystal 4280/461x + AC97 Audio, version 0.14, 13:39:25 Dec 4 2000 cs461x: Card found at 0xf8ffe000 and 0xf8e00000, IRQ 18 cs461x: Unknown card (FFFFFFFF:FFFFFFFF) at 0xf8ffe000/0xf8e00000, IRQ 18 ac97_codec: AC97 Audio codec, id: 0x4352:0x5914 (Unknown)
For 2.4.0-test10:
Crystal 4280/461x + AC97 Audio, version 0.09, 15:31:37 Nov 1 2000 cs461x: Card found at 0xf8ffe000 and 0xf8e00000, IRQ 18 cs461x: Unknown card (1028:0096) at 0xf8ffe000/0xf8e00000, IRQ 18 ac97_codec: AC97 Audio codec, id: 0x4352:0x5914 (Unknown)
The hardware is a DELL 420 dual P-III. The base linux distro is Linux-Mandrake 7.2. Filesystems are ReiserFS, running reiserfs-3.6.19 for test12 and reiserfs-3.6.18 for test10.
Note: The ReiserFS folks looked at this, but could not reproduce this on another smp machine. That was before I noticed the connection with cs46xx.
When I say the system freezes, I mean it completely locks up, and ALT-SYSRQ-<whatevercommand> does not do a thing. The magic key combo gives the expected result before freezup.
Thanks in advance for any help,
