2.4.9-13.1? Um, that kernel is not-yet-ready-for-prime-time.
We're rewriting the swiommu as that was one of the reasons for severe performance problems on ia64 and this was a first draft ... to be continued.
Does not occur with RC2 updated to 2.4.9-0.18smp kernel.
Error did not appear during 5 boots with qa1108 (2.4.9-13.3smp).
2.4.9-13.4 is now available at ftp://ftp.beta.redhat.com/pub/testing/kernel/ Please test and make sure we have not regressed on this point from 2.4.9-13.3. I'm going to close this now on the assumption that we have not regressed; if I'm wrong, please re-open it.
After many more reboots during other testing, saw this with qa1108 (2.4.9-13.3smp).
Reproduced with qa1108 updated to 2.4.9-13.4.
With qa1129 (2.4.9-17.3smp), reproduced a system hang at: "Bringing up interface lo:" This is one of the possible hangs I've seen when the initrd is loading the qla2x00 driver on a system with a qlogic 2200 card and attached storage.
I wanted to clarify that this issue was reproduced (as described in my previous entry) with the new qla2200 driver in the initrd. I remade the initrd using the qla2200 entry made by kudzu, which as you said is updated for the new driver. It is only in bug 55836 that I manually loaded the old qla2x00 driver mistakenly. BTW, The reason I was manually loading the driver is because the installer is not updated with qla2200 entries.
Did you also get: "Unable to handle kernel paging request..." messages with qa1129? Did you get a segfault?
I have not seen the kernel paging error or segfault yet, just the hang. But, like the hang, these errors are intermittent. I am attempting to reproduce all of them.
And on my very next reboot...kernel paging error, kudzu segfault, and hang at "bringing up interface lo:" w/ qla2200 driver in qa1129 (2.4.9-17.3smp).
I wonder if this really is the qlogic fault or the usb controller ;(
A nasty stack overflow has been found and fixed in the qlogic driver; it was found due to an oops like this :).... Should be fixed as of 2.4.9-17.4 (which Dell should already have)
Putting this bug in NEEDINFO state since we think it is fixed but need a while before Dell is sure since it can't be reproduced reliably.
This seems fixed. Haven't reproduced with 2.4.9-17.4smp after rebooting all day yesterday and today.
Great, thanks!
