Trouble with kernel 2.4.18-18.7.x

Hi, i've just installed kernel 2.4.18-18.7.x (from RPM) and now it seems there are problems with my scsi devices.
I have attached an adaptec scsi AIC7XXX adapter, the system detects the device, but in the logs appears messages: "blk: queue c24afa18, I/0 limit 4095Mb (mask0xfffffff)", these messages didn't appear before with my old kernel.

Also, there are another messages in the dmesg results:

kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter errno = 2

When i try to list or do something with my tape the message: st0 block limits 1 - 16777215 bytes appears...

Sorry i'm new in this ?

Is this a bug ? a big one ? should i use instead my old kernel ?

Thanks in advance,

Karina.

Thats a perfectly normal message. Its giving parameters for your scsi

That one is a bit stranger. I'd have expected it to put the scsi adapter in the initrd which apparently it hasnt

Quite normal.

So it looks like its ok. Do file the kmod: failed to exec report in
https://bugzilla.redhat.com/bugzilla however. Regardless of it not being a problem in your case it does want fixing

I get the exact same message on an intel L440GX (VA Linux) machine. I attributed it to the routing problem this board has. Looks like I was wrong or was I? FWIW I do not have any SCSI devices attached.

Assuming that you still want it in bugzilla if Karina does not do it I will. Karina if you do bugzilla this please let me know the number.

Enjoy,

Possibly not bugzilla worthy - it's /sbin/modprobe that's ENOENT, not the scsi adapter module itself.

This message is generated when the initrd loads scsi_mod.o and then sd_mod.o without loading any hostadapters first. init_sd does a scsi_register_module(MODULE_SCSI_DEV, &sd_template) which causes a request_module("scsi_hostadapter") in scsi_mod.o as the initrd hasn't yet loaded any hostadapters. The initrd then proceeds to load some the hostadapter drivers explicitly via insmod and everything proceeds fine.

Presumably if mkinitrd was reordered to load scsi_mod, first hostadapter, then sd_mod, etc, the message would go away but as it stands it is purely cosmetic.

It appears that recent RH build initrd files w/o all of the stuff in modules.conf. Perhaps only the first SCSI adaptor, perhaps just ignoring the ones which don't match the build hardware. I suspect the latter, since even using --with= in a manual mkinitrd failed (silently) to include the modules. I can't tell you how much that sucks if you build kernels for multiple machines on a compile server.

Also, I installed 2.4.18-18.8.0 and it put a bunch of overlong label= statements in lilo.conf, then ran lilo and didn't check the status. Since it had deleted the old kernel that left a totally unbootable system. Guess RH really likes grub and only tests upgrades and such with that.

I will report this later tonight when I'm willing to take the time to prepare a proper bug report.
