Ok, after much head-scratching and bisect-powered reboots I have disproved for myself that this is a kernel issue. Instead it's some weird interaction between certain BIOS settings on my motherboard (ASUS P5Q Premium) and my SCSI controller (HP SC11Xe, FusionMPT based) I use for tape specifically when there are no SCSI devices on the bus. Skipping the mptspi module, or connecting a SCSI device causes the problem to go away, ditto changing some settings in the BIOS that cause IRQs to be allocated differently. --=20 Robin Hugh Johnson Gentoo Linux Developer & Infra Guy E-Mail : robbat2@gentoo.org GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85 --Zs/RYxT/hKAHzkfQ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (GNU/Linux) Comment: Robbat2 @ Orbis-Terrarum Networks - The text below is a digital signature.
