Hello,
When activating the IDE SCSI option to have Linux know everything
about my IDE CD Recorder, I've an Oops at boot time.
Here are some details about my configuration :
- Motherboard Asus P4S8X, P4 2.4 Ghz, 512 MB RAM
- 1 SCSI Adaptec AHA 2944 U2W, driver AIC7XXX
- 1 CDRW TDK 4800B
- Some other IDE devices (IDE HD, IDE DVD)
Something that may help : There is an scsi PCI error Interrupt
which is only present when boot with 2.5.53, never seen it before
with 2.4.xx...
The oops at boot time :
...
