Hi there,
Tried to email the maintainer <[email protected]> as listed in the top of
drivers/scsi/ppa.c - but it bounced. There's no entry in MAINTAINERS for
this driver either.
Anyhow. Since upgrading the RAM in my machine to require CONFIG_HIMEM4G
(using CONFIG_VMSPLIT_3G) the PPA driver oopses with the following oops when
trying to write a file to the disc. The disc is in ext2 format.
If there's any more info you folks need from my system, please shout.
Additionally, please copy me in on replies since I'm not on the mailing list.
Thanks,
-- Michael
