- Subject: Kernel 2.6.18 - ALI15X3 driver too optmistic about UDMA

Package: linux-image-2.6.18-4-footbridge Version: 2.6.18.dfsg.1-12 Severity: important On the "cats" machines that we use for arm buildd work, it seems the kernel is too aggressive in enabling UDMA support for the onboard IDE chip: ALi Corporation M5229 IDE (rev c1) So much so, that simple data transfers are corrupted - the very first read from a disk to find the partition table in sector 0 is corrupted and the machine fails to boot. I've debugged through this to verify the problem, and for these machines for now I have built a custom kernel with UDMA disabled altogether. Trivial heavy-handed patch included here, but I'm deliberatly not setting the "patch" tag as I doubt you'll want to apply this as-is. --- debian/kernel/linux-2.6-2.6.18.dfsg.1/drivers/ide/pci/alim15x3.c 2006-09-20 04:42:06.000000000 +0100 +++ alim15x3.c 2007-04-16 00:25:17.000000000 +0100 @@ -378,6 +379,8 @@ struct hd_driveid *id = drive->id; #endif /* CONFIG_WDC_ALI15X3 */ + return 0; + if (m5229_revision <= 0x20) { return 0; } else if ((m5229_revision < 0xC2) && -- Steve McIntyre, Cambridge, UK. steve@einval.com < sladen> I actually stayed in a hotel and arrived to find a post-it note stuck to the mini-bar saying "Paul: This fridge and fittings are the correct way around and do not need altering"Attachment: signature.asc

Upstream says this is most likely a problem with the CATS firmware, and I never got any replies to my follow-ups questions, so I'm closing this bug report. Please talk to the vendor. -- Martin Michlmayr http://www.cyrius.com/
