IDE breakage
I'm experiencing serious problems with DMA (even normal DMA, not UDMA) on recent versions of -STABLE. Here's an excerpt from messages; kernel #3 is a recent -STABLE (yesterday's sources), while kernel #2 is 3.2-RELEASE. The config file for both is identical.

Re: IDE breakage
I'm experiencing serious problems with DMA (even normal DMA, not UDMA) on recent versions of -STABLE. Here's an excerpt from messages; kernel #3 is a recent -STABLE (yesterday's sources), while kernel #2 is 3.2-RELEASE. The config file for both is identical. I can confirm problems with DMA from IDE disks in -STABLE. The problems seem to have been introduced in $Id: ide_pci.c,v 1.28.2.1 1999/07/20 22:58:20 julian Exp $ And the effect for me is that the system stops in singleuser mode, with a "DMA failure" message. This is on a 440BX/PII-350 system. Reverting to 1.28 (from 17. January 1999) fixes the problems. Please back out 1.28.2.1, at least in -STABLE.

Re: IDE breakage
My fault I accidentally replaced a PAGE_MASK with a PAGE_SIZE. the resulting bug only changes teh behaviour on unaligned pages which are only possible on the raw device. (e.g. fsck) the Cyrix 5530 we used to test has a bug where we cannot do unalligned transfers by DMA anyhow, so we never hit this bug.. fixed in -current will be fixxed in -stable when I reintroduce the patch... julian On Thu, 22 Jul 1999 [EMAIL PROTECTED] wrote: I'm experiencing serious problems with DMA (even normal DMA, not UDMA) on recent versions of -STABLE.

Re: IDE breakage
Fwiw, I sometimes (mostly after a warm reboot) see: mmm dd hh:mm:ss hal /kernel: ata1: unwanted interrupt 1 status = ff immediately followed by a similar Fatal trap 12: page fault while in kernel mode. Last time, the current process was swapper. Next time it happens I'll write down the details. Power-cycling works around the problem. A kernel built on July 7th does not exhibit this behavior afaIct. -- Jos Backus _/ _/_/_/ Reliability means never _/ _/ _/ having to say you're sorry. _/ _/_/_/ -- D. J.

Re: IDE breakage
I'm experiencing serious problems with DMA (even normal DMA, not UDMA) on recent versions of -STABLE. Here's an excerpt from messages; kernel #3 is a recent -STABLE (yesterday's sources), while kernel #2 is 3.2-RELEASE. The config file for both is identical. I can confirm problems with DMA from IDE disks in -STABLE. The problems seem to have been introduced in $Id: ide_pci.c,v 1.28.2.1 1999/07/20 22:58:20 julian Exp $ And the effect for me is that the system stops in singleuser mode, with a DMA failure message. This is on a 440BX/PII-350 system. Reverting to 1.28 (from 17. January 1999) fixes the problems. Please back out 1.28.2.1, at least in -STABLE.

Re: IDE breakage
My fault I accidentally replaced a PAGE_MASK with a PAGE_SIZE. the resulting bug only changes teh behaviour on unaligned pages which are only possible on the raw device. (e.g. fsck) the Cyrix 5530 we used to test has a bug where we cannot do unalligned transfers by DMA anyhow, so we never hit this bug.. fixed in -current will be fixxed in -stable when I reintroduce the patch... julian On Thu, 22 Jul 1999 sth...@nethelp.no wrote: I'm experiencing serious problems with DMA (even normal DMA, not UDMA) on recent versions of -STABLE.
