Boot Hang with 1.1.0 No. 2

Post in this forum for problems at boot time, if there was no problem for burning the disc. For example can't find the CD, or strange errors when you press enter at the very first prompt.

Boot Hang with 1.1.0 No. 2

Post by musv » 13 Oct 2008, 06:40


like in the other Boot Hang Thread I have boot problems too with 1.1.0. In 1.0.4 everything works perfect. The problems occured for the first time in 1.1.0 beta.

My Config:
I use an old AthlonXP2600+. The CDRoms are SCSI and connected by an AHA-2940UW-Controller. In my regular installation I use the aic7xxx module.

The boot process is working until (I don't remember the exact sytax):
scsi:scanning atp870u

If I try to skip that module, then the system hangs at the next one. Thus I tried to skip the next 5 or 6 scsi modules, but it didn't help. So I switch back to 1.0.4.

I'm having a similar problem on v1.1.0 . Can't recall if the same happened on v1.0.4, but I bet this happens on the new version only.

I own an AIC-7892 scsi controller which should use the aic-7xxx driver.
The boot process hangs on loading the aic-7xxx module.

Booting with "rescuecd noload=aic7xxx" bypass the boot issue , but after that I can't obviously see any scsi devices.

I've found a solution.

There are two aic7xxx modules, 'aic7xxx_old' and 'aic7xxx' - loaded in the boot process in this precise order.

It seems 'aic7xxx_old' doesn't work for my card, and unfortunately prevents the 'aic7xxx' module to load correctly (it is likely that 'aic7xxx_old' hangs the scsi card...).

The solution is to prevent aic7xxx_old to load , so :

Code: Select all

rescuecd noload=aic7xxx_old,usb-storage
lets my system to boot correctly , with all devices correctly discovered.
I don't know why usb-storage must be excluded too, but I think it is a different issue.

Final note : a comment for Francois.

I've found that aic7xxx and aic7xxx_old drivers support mostly the same hardware.

I see no reason of loading both at boot time, starting with the old one!
In my opinion just the aic7xxx driver - the newest - should be loaded.

To ensure support with really old or odd cards, the aic7xxx_old can be left there and manually selected if needed.

Thanks, I changed that in sysresccd-1.1.1-beta7, the old driver won't be loaded.

Sounds good, now the boot process runs smoothly without any special kernel option (checked on v1.1.1 beta8).

Thanks for keeping up the good work!
