Hello Christoph,
Thanks for your answer.
Yes, I investigate about my kernel source (2.6.12) and I find that patches based
on a RHEL kernel sources have been applied. This explains the odd 2.4 sd.c.
Best regards.

Hi,
Due to SD_STATS=256 (/drivers/scsi/sd.c)
there's a limit on the max /dev/sd devices.
Now, we have a large FC fabric, with more than 3500 LUNs...
=> Of course, we have an Oops when an HBA is connected to the fabric
(still sd.c, BUG in function sd_iostats_bump when sd>SD_STATS)
What (bad) side-effects can be expected if we increase SD_STATS (4096
should be nice, may be 8192) ?
From you description it looks like you are using some odd 2.4.x vendor
tree. Just upgrade to latest 2.6 and these limitations will go away.
