Subject: 2.6.10-rc1 bttv oops in btcx_riscmem_free
Date: Sat, 30 Oct 2004 23:49:48 +1000 [thread overview]
Message-ID: <41839BFC.1070302@eyal.emu.id.au> (raw)
Watching on Mythtv, I stopped watching on the client. at this point
the picture froze. Looking in dmesg I see this oops. The machine
quicly becomes unusable ('ps aux' hangs).
I then applied the v4l patches off the list. Still the same problem.
Unable to handle kernel paging request at virtual address 85525fe9
printing eip:
c010b567
*pde = 00000000
