I also have the same motherboard and am having the same issue. Normal kernel works fine .. smp kernel gets jammed keyboard error. OK I have my dual desktops working now... I actually have the (SE7505VB2 intel motherboard w/latest bios). Solution: If you go into the bios and turn off usb 1.1 and boot up with smp kernel kudzu will ask to remove the configuration for root usb and 4 usb hubs. I removed the configuration, then rebooted into smp kernel, Kudzu re-detected the root usb and 4 usb hubs and that was it. Funny thing is, that if I put the bios back to the default configuration and reinstall os again, the problem doesnt happen anymore... --rod We have been having very similar issues with Supermicro 1U's - 2 Xeon CPUs, SCSI Controllers (either Adaptec or 3Ware), and USB keyboard. When using the SMP kernel with RHEL 3 or 3 Update 1, and "Legacy USB Support" on in the BIOS, sometimes I see the exact same error messages concerning "pc_keyb: controller jammed (0x1D)" - but, if I see the errors, the system seems to continue the boot and eventually all is OK. However, sometimes the boot hangs - just before one of these messages would be seen (if it were to continue booting). If I turn off the "Legacy USB Support", I don't see the problems. If I use the UP kernel, I don't see the problems. If I use an older version of Red Hat (such as 7.3 or 9), I don't see the problems. If I use an IDE based system (i.e. non-SCSI), I don't see the problems. Any thoughts or comments ? Thanks ... *** Bug 114202 has been marked as a duplicate of this bug. *** Any status on this BUG? If is really bad for us here. We see this exact same problem on our Supermicro boards (multiple models). Most often we have to reboot the system many times to get it to come up. We have two problems 1) Hang just after Hugetlb is displayed on the screen [when it does pass this, next message is the keyboard jammed] or 2) We boot up with many keyboard jammed messages and have not keyboard in filesystem check or kudzu. After it boots all the way we usually have the keyboard, but I would say 15% of the time we do not. All systems are SCSI based Raid systems. All systems are running the latest BIOS from Supermicro. This happend with all version of the Enterprise 3 system (U1, U2 and new U3). -Brett Morrow I also have this problem and am currently working around by disabling "Legacy USB Support" from the BIOS. PROBLEM: as mentioned above in SMP mode. SYSTEM: RedHat Enterprise ES 3 U3 (had problem with U2 also) SuperMicro X5DPI-GG (Motherboard) 3.06 GHz Xeon ( Dual ) w/ Hyperthreading Enabled 2 GB ECC Memory 3Ware 9500 SATA RAID Controller ( boot device ) It looks that SMM gets involved, althogh I do not discount a plain old bug in pc_keyb.c somewhere. Aldo, Rod, Brett: please reboot with kernel parameter "usb-handoff". Let me know if it fixes things. This bug is filed against RHEL 3, which is in maintenance phase. During the maintenance phase, only security errata and select mission critical bug fixes will be released for enterprise products. Since this bug does not meet that criteria, it is now being closed. For more information of the RHEL errata support policy, please visit: http://www.redhat.com/security/updates/errata/ If you feel this bug is indeed mission critical, please contact your support representative.

From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6a) Gecko/20031030 Description of problem: On Intel SE7500BR2 motherboard (with dual Xeon 2.0GHz, 2GB memory) multiprocessor kernel loose keyboard during boot. Console and dmesg says several times: pc_keyb: controller jammed (0x1D). Same problem was with all previous Enterprise Linux 3 ES smp kernels (no such problem with uniprocessor kernel) and on two servers (identical hardware), tested both PS/2 and USB keyboard. There was no such problem with RedHat Linux 8.0 on these servers. Version-Release number of selected component (if applicable): kernel-smp-2.4.21-9.EL How reproducible: Always Steps to Reproduce: 1. Choose smp kernel from grub bootloader Actual Results: During kernel boot see 'pc_keyb: controller jammed' messages, keyboard hangs (can not change any status LED) Additional info: Intel SE7500BR2 server motherboard (with latest BIOS) dual Xeon 2.0GHz 4x512MB PC2100 ECC memory sym53c1010-66 SCSI controller 4x36GB Hotswap Scsi RedHat Enterprise Linux 3 ES update 1
