Possible SCSI or ISOFS Bug in 2.4.0-test11

Possible SCSI or ISOFS Bug in 2.4.0-test11

[Niels Happel]

Hello everybody,

first of all: I am new to the linux-kernel list, so I don't know wheather 
writing here is allowed for everybody or developers only.

Anyway, here it is:

Hardware (SCSI-only system):

Tekram 390 U2W (SYM53C8XX support compiled into the kernel)
IBM U2W SCSI disks
HP DAT SCSI Streamer
Pioneer SCSI DVD
Yamaha SCSI CD R/W

Using kernel 2.4.0-test10 and earlier everything works fine. 
Using 2.4.0-test11 with the same kernel configuration an error message 
occured while accessing one of the mounted SCSI CD-ROMs:
"kernel: _isofs_bmap: block < 0"
Mounting them works fine, accessing them gives that error message.
It can't be an SCSI CD-ROM hardware failure, because the error message 
occured at both drives (Pioneer and Yamaha) and it doesn't matter which 
CD-ROM I am using.


Any hints?

Many greetings, 
                    Niels!

Same problem with ide-cs + ide-cd modules (IDE - PCMCIA)
kernel: _isofs_bmap: block < 0"
