From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.0-0.99.23smp i686; en-US; 0.8) Gecko/20010214 Using the kernel-smp-2.4.0-0.99.23 package (i686), the aic7xxx.o module crashes insmod on boot (as it loads the module from the ramdisk). Lots of register dump foo I will cut-n-paste by paper and pencil if you want it - it starts off with "NMI Watchdog detected LOCKUP on CPU1, registers:" Note that my scsi controller is an AIC-7899 U160M, which seems to feature prominantly in the bug list. Using the aix7xxx_old module instead works. Booting with kernel-smp-2.2.17-14, the stock aix7xxx works. Reproducible: Always Steps to Reproduce: 1. Try to boot using kernel-smp-2.4.0-0.99.23 2. 3. Actual Results: insmod locks up a CPU as it loads the aic7xxx module from the ramdisk. Boot stops, system hangs. Expected Results: It should have loaded the scsi driver, mounted the system disk, and booted.
This is actually a bug in the NMI lockup detection code. The latest kernel builds should have this solved already. Please verify that this is still a problem with the latest kernel, and if so re-open this report (note, it only effects aic7xxx_new and not aic7xxx now because it only happens with drivers that use the new SCSI error handling code and the original aic7xxx driver uses the old code).
