--- Comment #1 from Joe Feise <[email protected]> 2009-08-08 22:56:54 --- Slackware 12.2, using kernel 2.6.29.6
causes a kernel panic when udev initializes the SCSI devices.

---[ end trace bd6fcd56a304a4d0 ]--- Kernel panic - not syncing: Fatal exception in interrupt
The same kernel worked with Slackware 12.0.
The environment:
- Kernel 2.6.29.6, megaraid_mm and megaraid_mbox in the kernel (not modules, since I boot from the raid disk.)
- Distribution: Slackware 12.2
- LSI Megaraid 320-2 2-channel SCSI RAID PCI card, firmware 1L49
- Attached to channel 1: 1 RAID 1, 1 RAID 0 disks
- Attached to channel 2: 1 DVD drive using a SCSI-to-IDE adapter
- Megaraid boot option: unconf_disks=1
- udevd version 135
It works when I don't start udev.
