SubjectPROBLEM: Oops when modprobing alim15x3 (2.4.21)
[1.] Summary:
Oops when modprobing alim15x3 (2.4.21, 2.4.20 works fine)

[2.] Full description:
When ALi support is compiled as module, and I type
modprobe alim15x3
I get immediately kernel oops message. modprobe crashes with segmentation fault.

If the module is compiled statically into kernel, I get the following messages at
bootup, when a script runs hdparm -d 1 /dev/hda:

Jun 17 00:13:56 acerzone kernel: hda: dma_timer_expiry: dma status == 0x21
Jun 17 00:14:06 acerzone kernel: hda: timeout waiting for DMA
Jun 17 00:14:06 acerzone kernel: hda: timeout waiting for DMA

Jun 17 00:14:17 acerzone kernel: hda: lost interrupt
Jun 17 00:14:37 acerzone last message repeated 2 times
Jun 17 00:14:57 acerzone kernel: hda: dma_timer_expiry: dma status == 0x21
Jun 17 00:15:07 acerzone kernel: hda: timeout waiting for DMA
Jun 17 00:15:07 acerzone kernel: hda: timeout waiting for DMA
Jun 17 00:15:07 acerzone kernel: hda: (__ide_dma_test_irq) called while not waiting
Jun 17 00:15:07 acerzone kernel: hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
Jun 17 00:15:07 acerzone kernel:
Jun 17 00:15:07 acerzone kernel: hda: drive not ready for command
There is a delay of about one minute, then bootup continues. I don't know if this is related.

[3.] Keywords:
ali, alim15x3, ide, dma

[4.] Kernel version:
Linux version 2.4.21 (sys@acerzone) (gcc version 2.95.4 20011002 (Debian prerelease)) #3 Tue Jun 17 12:27:26 EEST 2003

[7.7.] Other information:
This is Acer Travelmate 332T laptop.

[X.] Other notes:
I didn't have problems with 2.4.20, with it DMA works just fine. 2.4.21
works also fine but without DMA.
The harddisk makes very strange sound, it makes sometimes "snapping"
sounds when idle, especially when starting to read something. There may
be also irritating about 1 sec delay.
I would believe that it's broken, my desktop harddisks have never made
that sound (unless they _were_ broken). However, this is brand new Hitachi
harddisk that I bought after the previous IBM Travelstar went broken
(and it also kept the same sound). Strange. But maybe new laptop harddisks
do this normally. And probably this isn't related to the above bug anyway.

No SMP support compiled in, ... let me know if you need kernel config.
