Subject: 2.6.17 + sym53c876 causes many i/o errors |
| 11 |

I just tried out 2.6.17 on my U80 (4x450, 2560MB), which boots off the |
| 14 |
onboard SCSI card (Symbios 53c876) from a sw raid1 of 2 disks. The disks |
| 15 |
are original Sun UW-SCSI Seagate 18G 10k disks, internal cabling is all |
| 16 |
original. Filesystem is ext3 with dir_index on. Distro is Gentoo, |
| 17 |
running ~sparc. |
| 18 |
|
| 19 |
Result: many I/O errors, leading to some filesystem corruption! I was |
| 20 |
lucky to notice and quickly go back to 2.6.15 and run a full fsck, which |
| 21 |
found some problems. One of the disks was marked failed by the raid1 |
| 22 |
driver, since it was returning lots of errors... it looks like the raid1 |
| 23 |
driver didn't give up as easily on the last disk, allowing the machine |
| 24 |
to still function. |

The old kernel is 2.6.15-gentoo-r7 installed via portage. Toolchain and |
| 27 |
utility versions from ver_linux: |

This is obviously a really dangerous bug, whatever it is, as it will |
| 49 |
easily cause corruption on the root filesystem before booting is finished. Both SCSI channels on the dual channel card return errors easily. This wasn't a |
| 50 |
problem on 2.6.15. |
| 51 |
|
| 52 |
Full kernel log from 2.6.17 boot to shutdown, and .config are attached. |
| 53 |
This kernel is gentoo-sources-2.6.17 from portage, let me know if you |
| 54 |
need a list of patches that are included. |
| 55 |
|
| 56 |
BTW, I can't fiddle much with this machine besides testing a couple |
| 57 |
patches. Doing a bisect to find the bad patch is out of the question. |
| 58 |
|
| 59 |
What gives? |
