Subject: [Linux-ia64] CMD649 driver in 2.5.5x
Date: Thu, 30 Jan 2003 16:37:12 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590709805780@msgid-missing> (raw)
As of 2.5.59, the CMD649 IDE driver is still completely hosed. It
reliably corrupts filesystems and trying to turn on DMA mode on a
zx1-based machine will cause an I/O TLB error. The backtrace starts
like this:
[<e0000000048c4b50>] sba_map_sg+0x410/0x7a0 sp=0xe00000003d6afc90 bsp=0xe00000003d6a94d0

Someone want to take a look?
