[SunHELP] BAD TRAP occurred in module "tl" ...

[Nicholas Dronen]

The module 'tl' is /kernel/drv/tl.

$ modinfo | grep tl
 54 f5b91d4d   22b1  14   1  ttcompat (alt ioctl calls)
 61 f5bbe037   44df 105   1  tl (TPI Local Transport Driver - tl)
 81 f5fce000   1a99   -   1  tlimod (KTLI misc module)

It has a bug, apparantly, wherein it tries to copy or read
data from a user space address, and the address is bad.

Regards,

Nick Dronen
