I'm sure someone will correct me if I'm wrong but was there ever such a limit for IDE drives.
The limits are 528Mb for non-translating BIOSes, 8GB for translating BIOSes and 136/137Gb for CHS/LBA actually on the drive.
DOS 16bit VFAT partitions *are* limited to 2GB (65536 clusters of 32k) and some translating CHS BIOSes apparently do have problems wth > 4092 cylinders (according to the notes that came with my 3GB Fireball). Also some of the software patches to do CHS translation may affect Linux because the drive geometry may appear differently to Linux and DOS.

Well I'm running Redhat 4.0/2.0.28 on a 3GB Fireball without problems. My system is dual-boot between Linux and Windows 95. Given the symptoms that you describe it may be a BIOS problem but it's hard to say given that you haven't said what Kernel version had problems, what processor/motherboard/bios/bios version you have, nor whether you are using software to do CHS translation for Windows (eg Ontrack or EZ-Drive)
