From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2 i686; en-US; rv:0.9) Gecko/20010507 Description of problem: A Qlogic 2xxx series card, in this case a qlogic 2100, will install perfectly when placed in the 64-bit slot but will fail when the card is placed in the 32-bit slot. It will lock up at loading qla2x00 module. I do have the card in case anyone would like to test it. I have attempted to install using "expert noprobe" and "options=verbose". Both times the install locked up when loading the module and I was not able to switch to any of the other virtual consoles. How reproducible: Always Steps to Reproduce: 1.place card in 32bit slot. 2.start standard install 3. Additional info:
I'm having the exact same problem with 2.4.6-2 and a 64bit QLogic 2200; hard hang on loading the module. No oops, but machine is dead, no VC's, no <alt><SysRq>, etc.
Also seen in RH 7.2 Beta 3. Bugzilla #50703.
This is believed to be a Intel firmware issue
Fixed in 2.4.9-21 kernel errata.
