Description of problem:
When i start the mirror (re)build (mkraid or raidhotadd) the System
will unexpectly panic with "Killing Interrupthandler"
Disks From other manufactor does'nt have problems (Seagate, ...).
I've make a Kernelupdate on 2.4.20-30.9 and see the same problem.
Also there is no way to get the System up with Fujitsu Disks.
Code: 8b 01 85 45 f0 75 1c 8b 02 89 d3 89 c2 0f 18 00 39 f3 75 e9
<0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing
I use two Fujitsu MAP-3367NC disks in with Intel SE7501WV2
Serverboard and the onboard SCSI controller.
Version-Release number of selected component (if applicable):
raidtools-1.00.3-2, under Kernel 2.4.20-8bigmem
Steps to Reproduce:
1. Make 3 Partitions on two Fujitsu 36Gb SCSI disks
2. Setup /etc/raidtab
3. start "mkraid ..." on all partitions
Actual Results: A installaion will work till the first boot! When
the System is in rebuild of /dev/md3 it will panic.
A few comments. First, this isn't a raidtools bug. It's a kernel
panic after raidtools has already done its job. Second, raidtools is
deprecated, you should use mdadm instead. Third, to know what's
panic'ing I need to know the controller and driver version that the
Fujitsu disks are connected to.
I'm sorry for the delay...
Ok, so I think it must be a timing problem between the Fuji disks and
I have only this Problem with disk mirroring, Fuji disks and RedHat
9. When I use RedHat AS 2.1 or AS 3.0, or Seagate disks the problem
The output from "/proc/scsi/aic79xx/0" is (where the Fujitsu Disks
Adaptec AIC79xx driver version: 1.0.0
aic7902: Ultra320 WideChannel B, SCSI Id=7, PCI-X 67-100Mhz, 512 SCBs
By the way: I'm using now Seagate disks with the same configuration
and they are working now for 2 Weeks without problems.
I think this is a known issue between the version of aic79xx driver
and the version of firmware on the Fujitsu disks. Either an updated
aic79xx driver or an updated disk firmware should solve the problem.
I'm closing this out as NOTABUG since it's a firmware interaction
issue (which we obviously can't do anything about Fujitsu firmware,
and I think the later aic79xx driver just enables some sort of
workaround, but if you get the updated firmware then the workaround
