It This wasn't about hot swapping in my case. On the hot swapping thing, I've never successfully done this with a 2.6 kernel. > seemed that the bus reset that the backplane processor generated > caused trouble for the driver, killing the SCSI bus. 2.6.16 and > 2.6.17 locked up the kernel in the case of hot-swapping drives. I have a scsi box that supports hot plug. I had a drive failing and I decided to just replace it, took down the entire bus and the raid array with it, fortunately, nothing lost.

As stated in the email, it was the aic7xxx driver. I've never had problems with the u320 driver that I recall since I've had this machine. It appears that when I load aic7xxx, it finds both channels of the u160 card and all it's devices, then when it hits the 2940u/uw card, it loads the first channel, all devices and crashes before it hits the 2nd channel. It looked like it had problems with the plextor cdrw thats on ID2. But the odd thing is, if I boot to /bin/sh, insmod aic7xxx, and exec init, everything's fine. -- Lab tests show that use of micro$oft causes cancer in lab animals Got Gas??? - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
