Hi James,

unloading the lasi700 scsi module hangs my PARISC-machine:

hw1306:/# uname -a
Linux hw1306 2.4.16-pa25 #2 Thu Dec 27 13:03:15 CET 2001 parisc unknown

hw1306:/# modprobe lasi700
53c700: Version 2.6 By James.Bottomley@HansenPartnership.com
scsi1: 53c710 rev 2
scsi1 : LASI SCSI 53c700
scsi1: (2:0) Synchronous at offset 8, period 236ns
  Vendor: TOSHIBA   Model: CD-ROM XM-3601TA  Rev: 0725
  Type:   CD-ROM                             ANSI SCSI revision: 02

hw1306:/# lsmod

53c700                 28396   0  [lasi700]
....

hw1306:/# rmmod lasi700
<machine hangs and only responds to pings, no login possible>

The machine is a B180L with an integrated 53c875 (scsi0, compiled into kernel)
and one 53c700 (scsi1, lasi700, as module) with one external CD-ROM drive.

Any ideas ?

Thanks,
Helge
