System: PCI-less 486 w/83 MHz Pentium overdrive, Micronics systemboard 32 MB RAM, 1 GB SCSI disk as root partition, SCSI CDROM VESA Local Bus, Adaptec 2842 SCSI card, VLB ATI Mach32 During the initial portion of the installation, the installer is told to use the SCSI CDROM for installation. It inserts the aic7xxx module, the SCSI devices are probed seemingly normally, but at the end of the usual 5 second SCSI timeout period: Kernel Panic: aic7xxx: unrecoverable BRKADRINT In swapper task -- not syncing The aic7xxx module loads correctly, without options, in 2.2.12-20, 2.2.13, and all tested 2.3 kernels up to and including the 2.3.99-pre4 series. Alan Cox's releases of the 2.2.15-preX series were not tested. Sanity checks: A separate boot floppy was created from CDROM, from the files in the zoot-i386.iso image. All RPM's in the iso image checksum correctly, as does the MD5 checksum on the entire image. Both boot floppies resulted in the same kernel panic. The system is being upgraded to RH 6.2 manually. -Craig
I have (verbosely) compiled aic7xxx from 6v0 distribution which works and compared with 6v2 distribution aic7xxx which fails - the only (reported) difference being the 6v2 aic7xxx generates the message: "May 15 19:25:17 duality kernel: enable_irq() unbalanced from c888694a" before the kernel panic which occurrs immediately after: "May 15 19:25:17 duality kernel: (scsi1:0:-1:-1) Scanning channel for devices." I can provide any info required from a Dual Pentium EISA 274x SCSI platform, email me.
The current aic7xxx driver version (5.1.31) solves the problems with BRKADRINT panixs on aic7770 based controllers including the 2842VLB controllers and the 2742 EISA controllers.
