Sorry, i couldn't find a "freeze" label in sil_interrupt(). There's one
in sil_host_intr(), but appending 'printk("THIS VERSION RUNS MODIFIED
sata_sil!");' there, doesn't have any effect (it doesn't get printed
out). That's the only freeze label i found in sata_sil.c. My original
drivers/scsi/sata_sil.c was version 2.6.18-rc1.

'strings /lib/modules/2.6.18-rc1/kernel/drivers/scsi/sata_sil.ko'
doesn't give any unexpected results:

The kernel was built with Debian's make-kpkg (make-kpkg --initrd
kernel_image). Output is still the same.
