I have some SCSI troubles with 2.6.5-rc1 (from BK) that 2.6.4 didn't have. Modprobe, loading the st driver, tries a NULL pointer dereference in kernel space and my 2nd tape drive isn't found: st1 is not shown. cat /proc/scsi/scsi (typed after the attempted zero page dereference) hangs in rwsem_down_read_failed with process state D. I've re-built the kernel after doing a "make clean" but to no avail (as expected). ... sym0: <875> rev 0x26 at pci 0000:00:0d.0 irq 16 sym0: Tekram NVRAM, ID 7, Fast-20, SE, parity checking sym0: SCSI BUS has been reset. scsi0 : sym-2.1.18i Vendor: FUJITSU Model: MAH3182MP Rev: 0114 Type: Direct-Access ANSI SCSI revision: 04 sym0:1:0: tagged command queuing enabled, command queue depth 32.
