From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.4) Gecko/20011019 Netscape6/6.2 Description of problem: SCSI bus reset when trying to read Quantum Atlas IV HDD. This happens only when Adaptec 39160 (7899) hooks up to Hendrix. However, if I configure to use ROMB and create a RAID, then the HDDs are working fine (use aacraid driver). Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.A server with onboard 7899, or 39160 card + Hendrix + Quantum Atlas IV HDDs. 2.Boot from CD, and switch to VC 4 to see the errors. 3.Use the same Hardware configuration but ROMB instead of SCSI. There is no time-out occurs. Actual Results: Failed to read, identify, use of Quantum Atlas IV drive. This also happens on IBM drives too (U160). Expected Results: aic7xxx driver should work with those drives when they are in Hendrix. Additional info: Also, If using those HDDs as internal drives (Not plug-in to Hendrix), then they are working as expect.
Could you try the aic7xxx_old driver to see if that one works ? (to see if it's driver or hardware)
Created attachment 47980 [details] dmesg
aic7xxx_old driver does the same thing.
I can "insmod aic7xxx" when I use UP kernel. fdisk, mke2fs work fine also. This problem seems to happens on SMP kernel only (well, maybe on bigmem kernel too).
Can you try the pensacola beta.40 kernel? this can be one of those interrupt bugs ;(
Pensacola is working fine (beta.40 kernel).
So, did the patch from Pensacola make it into the Hampton kernel?
fixed in beta3
