pata_ali complains at boot

pata_ali complains at boot

[Taneli Vähäkangas]

Hello,

I'm using pata_ali with ULi M1697, which has this:
00:16.0 IDE interface [0101]: ALi Corporation M5229 IDE [10b9:5229] (rev c7)


IDE works with either pata_ali or alim15x3, but pata_ali complains
at boot like this:
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2
ata2.00: (BMDMA stat 0x24)
ata2.00: cmd c8/00:58:30:00:00/00:00:00:00:00/e0 tag 0 cdb 0x0 data 45056 in
         res 51/84:00:87:00:00/00:00:00:00:00/e0 Emask 0x10 (ATA bus error)
ata2: soft resetting port
ata2.00: configured for UDMA/100
ata2: EH complete

This is repeated a few times, only with different UDMA levels.
Is this normal? Or at least not dangerous ...


I'm running libata-dev git tree as of tuesday plus a patch to
libata-core.c:ata_exec_internal from Tejun Heo, without which
it just oopses. ata2 port has only one drive:
ata2: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xFF08 irq 15
ata2.00: ATA-6, max UDMA/100, 390721968 sectors: LBA48
ata2.00: ata2: dev 0 multi count 16


(Please copy responses, I'm not on the list.)

What rate does it stop at ?
